Enhance Performance with 6 New NGK Iridium IX Spark Plugs TR55IX # 7164 Review

Very glad I spent the extra money on these plugs. For an extra $10 over other spark plugs, a worthwhile investment considering they last over 100,000 miles, you can't go wrong. That's about $1 a year for a much smoother, more economical, and easier launch. They are everything they say, very, very happy.

I switched from a DENSO TT that didn't last long. In addition, I immediately notice the difference in performance thanks to the smooth running of the car. They are a great choice, I would highly recommend them and will be buying more in the future. Excellent seller sent on time received on time.

Perfect spark plugs for my 2008 Chevy Silverado 1500. Great replacement. My Silverado is now working like lightning. To be fair, the original works Autolite cars have done 50,000 miles and probably should have been replaced much sooner. Anyway, I'm an NGK fan and they don't disappoint with the Silverado.

According to Revane's "Your Garage" these spark plugs "will fit" my 2002 Buick Rendezvous. After all 6 spark plugs and wires were replaced the "Check Engine Soon" light came on, the code was P0301, Cylinder 1 Misfire. Couldn't find any problems with my work or damage from the replacement, I had to take the car to a workshop. After $150, they confirmed the spark didn't fit GM vehicles. I have to use the AC Delco brand! What a waste of time and money!

Used on a 2006 Pontiac G6 V6 sedan. Basic model from 3.5. This was my first time making spark plugs and I was worried I would get it wrong, but it turned out fine. Don't forget to change the wires too! My engine was at almost 150,000 and cylinder 6 was misfiring so I figured my spark plug was to blame. These new plugs are amazing. The engine sounds better than with the OEM spark plugs and I feel it has a slightly more responsive feel. Although maybe it's just because I'm used to it not working…

I bought these candles for my 2005 Chevy Astro. The van has about 200,000 miles and its rusty support is falling apart. The only reason I changed the spark plugs in the first place was because I want to get as many miles off the van as possible before it falls apart. With the old spark plugs stalling him all the time, that was next to impossible. Since these NGK connectors are about $30 cheaper than AC DELCO, I decided to give them a try. I already installed the spark plugs at the end of May…

We received our '01 Tribute in 2000. I thought that was it when we were struggling to get to 30mph and the EGR valves started blowing . I took care of the clogged catalytic converter but the engine still ran intermittently. I took a chance and bought a full set of ignition coils, these NGK spark plugs, a set of upper and lower intake manifold gaskets and a PCV valve. I was surprised by the mixed reviews about the quality and results of another big brand fork that I like. NGK was there and…
