## Description

Denso (4702) IK20TT Iridium TT Spark Plug, (Pack of 1)

Review: Smooth Performance and Better Fuel Efficiency! - After switching to the Denso Iridium TT spark plug, I could immediately notice the difference. My car now runs much smoother, with a more balanced and harmonious performance. Acceleration feels cleaner, and the engine responds effortlessly. One of the best parts is the noticeable improvement in fuel economy—I’m saving gas while enjoying a more comfortable ride. The quality of this spark plug really stands out, and installation was quick and easy. If you want better performance and fuel savings, this is the spark plug to get.
Review: Male sure you get them in the box pictured - Make sure you get them in the sealed box pictured, box top was sealed shut, I opened it and inspected all four since this is my second order. All were in perfect, untouched appearance. Gaps all uniform, electrodes line up perfectly, gap appears identical in all four, and the firing end protected by cardboard tube. Also, these came in a 6x6x6 heavy made box with a few air pouches...well protected. My first order of four came in an envelope, no outter box like picture, haphazardly just thrown in, all four loose to move around in the envelope, two where actually out of their boxes just tumbling around in the envelope. Two of these four even had been gapped wrong and the electrodes did not even line up. Easy fix these used four are going back to desertcart and should have never been sent out in such shape. Hope the picture and the above that I went though to get four actually new, untouched plugs helps others. Accept nothing but the sealed box, otherwise you're likely getting problematic plugs like I did, send them back.These are excellent plugs, I have used these before and know this first-hand. I feel some if not a lot of the negative reviews come from subpar plugs being shipped and installed, creating running problems. I definitely recommend the properly handled, packaged, and shipped plugs! 💯 Percent.

**Q: this sparks plugs fit with the honda civic 2002 ex vtec?**
A: God

**Q: are these gapped at 0.4 and are these able to be gapped to a different size?**
A: i belive i double checked and they are all pre gapped very accurately.  i dont remember if its gapped at 0.4 but i know for sure you can re gap them to whatever spec you want.  I think on my bmw the pre gap is narrower but i installed them anyways due to the gap might widen as you hit more miles?  so it will still be within spec.  I was told a little narrower gap creates better jump of current so i might have an increase of 1 or 2 hp?

### ⭐⭐⭐⭐⭐ Good quality plugs
*by J***Y on June 18, 2024*

Put these in a Honda Fit so I had to gap them some. The factory gap was really consistent on the set and they were easy to gap out some. Went in no issues and are performing better than the Autolites I replaced them with.
