Spark plug Denso or OEM Honda

if you want some good plugs, get some denso IKH24, they are 1 step cooler than stock plugs.. I change mine out every 20k miles..

IKH 24 plugs with stock coils work just fine. No cutout, rough idle or misfire.

Replaced stock with denso ihk24.

denso ik22 works also, also an iridium tipped plug

I bought a box of denso.

Everyone has been praising (fleet vehicles).

Im with the Densos already and the spool and throttle response is so much better. Even with gap 0.075mm they are much better.

I have the denso ikh24 and no problems for me.

ive ran the denso plugs in my stage 2 gli, and they worked great, had no issues with them.

Just an update for you and a PSA: CHECK YOUR SPARK PLUG GAP ON NEW PLUGS. I too trusted that the iridium plugs that I just bought should've been pre-gapped, but I noticed immediately after a tune-up my gas mileage went to piss. Popped the plugs back out and sure enough each one was well over 1mm .

I installed brand new denso ik24 plugs gapped at .026 and I am still getting misfires.
