Reviews of Denso spark plug

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.

the tips of the IKH24s break off in expensive TTRS engines.

I have the 24's, not impressed.

For what it's worth, I've changed my plugs twice (OEM to Denso to Beru-RS7) and never noticed any oil or any difference in color between the plugs.

the densos work fine, the point of swapping is not for any performance gain, rather to prevent shattered ceramic from raining into your cylinders
