Wow what a difference
My cherry 2002 Suburban 1500 LT 2wd runs now like it is brand new. CANT even feel it running when it’s idling. It had ACDelco platinum plugs in it that had wear and at .60 gap when should be at .40 . Now I barely put my foot on the pedal and the responsiveness is excellent. It’s accelerates and has great torque. Big plus is also Im very sure these are not fakes. ... show more

Good spark plugs for good price, seems to work very well. I plan to change my plugs at 50K miles. They came gapped at 0.040”, some places says they’re gapped to 0.044, the OE gap for my vehicle is 0.040 I used the Laser iridium as they’re good for 80K miles, the iridium IX is good for up to 50K miles. Recommendations: I added a small amount nickel anti-seize to the threads due to the carbon buildup on the old plugs. Dielectric Silicone paste on the boots goes a long way, I used Mission Automotive silicone paste. Overall I would buy again. ... show more

Authentic gapped perfectly plugs
Seems legitimate for my 2014 Yukon. I have one bad plug throwing my engine off. First set of plugs that came in with the wrong plugs. Contacted Amazon and sent those back in. These were delivered within the next two days. Changed the one bad plug in my engine and now it runs as smooth as silk so I will be changing all of the plugs in my truck. Just waiting on my plug wires to come in to do that. Highly recommended plugs. Authentic and fit perfectly. Al gaps were exactly .040 as stated and believe me I checked every single one. ... show more

OEM Quality Spark Plugs
These NGK IZTR5B11 spark plugs are excellent OEM style replacements. Fitment was perfect and installation was straightforward with no issues.

Very good price & Excellent quality
These are the correct spark plugs for GM 4.8 thru 6.0 liter engines, they were also set to the revised factory spec of .40 of an inch. They were packaged well and shipped with collars around the threads, to not only protect the threads, but also the electrode from being bent if package is dropped. If these maintain their price of roughly $64 for 8, then this is a great deal. My truck's 4.8 runs smoothly and power is very good, I would dare say feels like a brand-new truck. So far these have worked well, I am also using the Edelbrock 22716 Ultra Spark 50 spark plug wires, will come back and edit review if the spark plugs fail for some reason. Currently I highly recommend these spark plugs. ... show more
