Reviews of Denso spark plug

I run the Denso.

Denso 5749 non projected

I got some good tips from the community and went with Denso IKH24. Also bought a gap tool to properly gap them. Im planning on swapping them out every 8k.

Im running denso step 2 cold plugs from bms website and tbh i regret not going with the hks plugs

Almost everyone either runs the HKS plugs or Denso plugs. I personally have had no issues running the Denso plugs.

I use [Denso IKH24's](https://www.fcpeuro.com/products/audi-vw-spark-plug-denso-ikh24). It's the projected tip version of the Denso plug EQT has recommended on their FAQ (IKH01-24).

I got some phony Denso marked spark plugs

I bought the plugs from Toyota (Denso). I asked for the old plugs off. The plugs I got back were NGKs that were installed at the factory. I can’t say I notice a difference really (except new plugs did seem to make a difference).

Porcelain tip fell off one Denso spark plug in cylinder 1. Doing less the 200km distance. Motor is f@$ked.

Use only Honda specified plugs (usually Denso Iridium) and they last 100,000 miles just fine.
