Which Chevy Tahoe years does this reference cover?

The cited NGK TR5IX application listing covers 2006–2014 Chevrolet Tahoe LS models with the 5.3L V8. Those model years are 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, and 2014. Pulstar’s March 2024 chart maps NGK TR5IX to IAD1H10.

Match your exact engine and application before ordering. This listing does not establish coverage for every Tahoe trim, engine, hybrid configuration, or later model year. If your Tahoe differs from the listed application, ask us to check it.

Can Pulstar help your Tahoe deliver more?

A Mustang Dynamometer report for a 2012 Chevrolet Tahoe 5.3L FFV records higher peak power and torque in two runs than in the stock comparison run.

Both Pulstar runs recorded peak power of 236 hp, compared with 229 hp for the stock run: a difference of 7 hp. Both also recorded peak torque of 239 lb-ft, compared with 231 lb-ft for the stock run: a difference of 8 lb-ft.

These are reported peak values, not gains at every engine speed. They provide a measured example of higher output in the tested Tahoe, rather than a promise of identical results for your vehicle. View the 2012 Tahoe 5.3L dyno report.

Choose the right spark plug for your Tahoe

Have your Tahoe’s model year, engine details, and specified plug number ready. If your exact application specifies NGK TR5IX, Pulstar IAD1H10 is the corresponding reference in our chart. If your vehicle has an engine swap or other modifications, have your installer check the actual engine rather than relying on the original vehicle specification.

Follow the vehicle and spark plug manufacturer's installation guidance for gap, tightening, and service requirements. Do not assume that cross-referenced plugs share identical installation instructions or replacement intervals.
