I've just begun a second YouTube channel at https://youtube.com/@motorcycletechandtravel. I will be riding the 2000 Honda XR650R and '84 Honda XR350R extensively for videos. I need these bikes to perform well and start easily on camera. Pulstar spark plugs excel under these demands.

I have them in my 1970 jaguar E-Type and the performance improvement has been phenomenal including better gas mileage. I don't have but a couple of hundred miles on them but I sure like the additional performance they are giving me.

I`ve used Pulstar plugs in some of my former vehicles and I was mostly happy with the results. So I decided to try them in my current bike and truck. [On my Bike], the engine starts quicker, runs much smoother, much better throttle response. [On my truck], the engine starts quicker, much better throttle response, entire vehicle feels a few hundred pounds lighter. In short, I’m overwhelmed!!

Super easy to install. ECM takes about 20 miles to “learn” even when battery disengaged during install. This morning drove around town. Performance so far about 40 miles is off the charts better than anything since car was new! 144,000 miles. Superb! All the superlatives one reads about are there. Very, very impressed! I had just replaced AC Delco plugs with Denso TT’s a month ago which was a large improvement over ACD plugs. Still, the idle ain’t right. That’s why I decided to try the Pulstar’s. Boy am I glad I did!

Hello I just purchased the 1BEH1 spark plugs shipped to Australia, first drive around the block on LPG (duel fuel) Nissan VG3.3 was a big improvement overall, really happy. How many kilometers can I expect before replacement and are these iridium or platinum plugs? Thank you.

I have tested your spark plugs on our custom built Mazdaspeed 3 Generation 1 2008, I have custom R35 Hitachi Coils and paired them with your IEF1H 10 plugs and I can say, I have huge gains in the low end and no spark blowout in the top end, my car needed to be remapped to suit the bigger spark as I was getting more boost throughout the whole rev range.

Pulstar spark Plugs arrived last week. Mounted them on my Gpz Turbo and made a 120 kilometers journey on Saturday with my Turbo motorcyle! They behave really really good! They have best torque and hp on all engine range and idle is really more smooth compared with previous NGK iridium spark plugs. I’m very satisfied and just made a really positive review on my motorcyle forum!

I picked up a set of Pulstar plugs for both my Camaro SS and Audi TT. Both of which are used for autocross and track days. The difference you feel after upgrading to a set is immediately noticeable. I highly recommend giving them a shot in your application if you're looking to squeeze a few more horses out of your engine.

I have been using Be1H10's in my 2003 6G74 Diamante V6 for the last 6 months and can say they are the BEST plugs I have EVER TRIED..!! There is a REALLY NOTICEABLE increase in both POWER and in economy at cruise throttle openings, and a very strong steady idle... Now I am waiting for a set of IBe1H10's to arrive...can't wait to fit them!!

These are not your latest Fad of a spark plug, They work awesome as stated. After all these years of trying every spark plug brand out there. I now am beyond happy with these plugs since I can actually feel the consistent power from zero to my top end. Now the Pulstar's are going in my fleet! I cant wait to try them in my snow machine.

The change to Pulstar® plugs gapped to factory 0.035″ was the only change made for this test. We waited for the first tank of fuel to burn through before making comparisons. At that point there were several distinct improvements: Better tip-in throttle response at any road speed and under heavy acceleration. Less throttle needed to sustain normal “cruise” road speeds. Less downshifting on grades with cruise control applied. Acceleration improved with both forced and cruise control downshifts. Distinct improvement in fuel efficiency; approximately one mile per gallon improvement (5.5%) under “city” and “highway” or interstate test conditions; this engine has always started well.  Click here to watch the video.

I just wanted to follow up and thank you for sending through the spark plugs for my 2013 Camaro SS 1LE. I attended the SCCA National Champ Tour New Jersey this weekend and took home a first place finish. ...I just wanted to share with you as a thank you. I really love the product and am proud to promote my success with them.

I don't really write reviews… but I felt I had to with these plugs. I researched the website and technology and it made sense. I had no idea a spark plug could make such a difference in performance until now!! I have a 2014 EFI Triumph Bonneville - I have added a ton of performance upgrades and even remapped the fuel injection for more performance... All of the upgrades made a difference.. but none as dramatic - nor a bigger bang for the buck - as swapping out my plugs for these. I will put these plugs in anything and everything I have a spark plug in if possible. To me it's a just a no brainer. Do yourself a favor and get them.

I tried a car while using Pulstar... the performance is totally different from others, high power! Smooth! Rapid react! Even the engine sound also great a lot- Marvelous! I love it!!

The car feels snappier, more responsive to the throttle than before...it feels noticeably stronger and I’d be willing to bet it is stronger and probably in the vicinity of the 5-7 hp gain Pulstar documents were achieved in the Tahoe as well as a 2012 Charger.

Hard to separate out the products but I paired Pulstar plugs with Top Street Performance (TSP) coilpacks (45kV) on my 2014 V6 3.7l mustang and instantly stronger idle with better low end shift control. Typically my auto shifted into the 1.00 ratio 5th gear at 45mph and held it down to 41mph. With the Pulstar + TSP combination it still shifts at 45 but will hold it down to 39mph. Likewise. when going uphill on the highway (65mph) it used to down shift from 6th gear (ratio 0.70) into 4th gear (ratio 1.23) at 55mph (mind you, uphill load). Now will hold sixth overdrive on the same middle TN hills down to 50mph. Lastly, are you sitting down, first 64mi (and the real reason I'm sending this comment) about 50:50 mix of city and highway = a clean 30mph. 64mi = 2.11 gal (monitored through OBD2 reader). I have to believe it is improving my low RPM torque.

Got these, installed them into my Jeep, and so far, it's been running smoother and more economical than before. Previously, I was getting ~15 miles per Gallon, now it's 20 MPG. Horsepower has increased, and the acceleration is faster than before.

I put them in my '64 lancia flavia replacing very good champion n3 plugs. I set the car up for a fast idle at 1100rpm and after the plug swap the idle was 1400rpm and the mileage went up about 10%.

I came across Pulstar spark plugs in some 4x4 enthusiast forums, and after looking through their website I was so impressed with all the background information provided (both the level of scientific analysis, and the sheer volume of empirical data) that I decided the generally high-price was justified, and I would try the plugs in my own vehicles (a 1989 Landcruiser and a 1997 4Runner). IMMEDIATELY I noticed an improvement in throttle response; it was particularly obvious in my 4Runner which suffered from an 'engine stutter' issue that I had been trying to properly diagnose and fix for about a year. Right away, the stutter issue went from being noticeable in approx 15-30% of certain throttle situations to scantily noticeable at all, and when it is noticed it's only in approx 0-5% of the same throttle situations. I also noticed a significant improvement in fuel economy. I am almost religious when it comes to calculating my overall fuel economy for the last tank of gas after every fillup (I even know exactly how much my different-than-factory-sized tires impact odometer readings on both of my trucks, based on distance comparisons between odometer vs. GPS data) and prior to changing the spark plugs I would average between 16-18 MPG (often in the high 16s - mid 17s, and only reaching 18+ on tanks that were nearly 100% highway miles at cruising speed) in the 4Runner. Now, since installing Pulstar spark plugs, I've filled-up 4x tanks of gas in the 4Runner (none yet in Landcruiser) - and on the first three (which were no different from my normal weekly commute to/from) I averaged 18+ MPG (up to 18.5) and on the last tank, which admittedly was quite favorable in that it was 260+ miles all on the highway at cruising speed (not more than 75mph) and coming from Bishop CA to Los Angeles CA (an overall drop in elevation of about 3,000ft) I averaged an ALL-TIME-HIGH overall 20.1 MPG!

I have used pulstar plugs twice now on two different engines and both times was very satisfied with the results. I noticed right off the bat that the idle got smoother and seemed to be able to run quiet and slower. It didn't seem like the engine had to work as much for a very smooth idle. I had seen several YouTube videos from customers and independent sources that shown how much hotter the spark is and it's very noticeable the increase of spark. I noticed my fuel mileage had increased a few miles per gallon and again the engine seemed to be able to accomplish the same tasks with less effort than before. Power is something else you notice. Besides the dyno charts you can find online, you can feel more as the power band is stronger. I always thought the talk of in the past when people would talk up certain spark plugs just was always something you could sit back and laugh about as plugs never seemed to make any power changes. Well these plugs proved me wrong as without a doubt you can tell how much better the engine runs and feels stronger as well as you can 100% find tons of dyno results showing they indeed do. Again you can search YouTube for results by independent people. Also since I have run my own tunes on two different engines, the spark charts can be pushed a little better as it seems to respond better. I am extremely satisfied with these plugs.  I had called with a question and I was given a great answer from a very knowledgeable person.

I had a choice between good performance on short drives, or good performance on longer drives, and always bad performance in cold weather. After I installed a set of Pulstar plugs, I put the stock idle feed restrictors back in and leaned out the idle. Now, throttle response from a cold start is flawless and throttle response remains so even when the engine is fully warmed up. As soon as the snow melted, I went for a 90-minute drive in 30-degree weather covering all conditions from country roads to freeways to city streets without a single stumble. I went for another long drive on a recent 65-degree day with perfect performance again. On both drives I found I was more likely to hit the rev limiter in first and second gears so power may be up as well. To summarize, I thought the only way to solve the drivability problems was to replace the carburetor with a fuel injection system, but just installing the Pulstar plugs was enough. I am extremely pleased with how these plugs work.
