Very, very impressed!
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!
