Denso 4511 Platinum TT Spark Plugs in Vortec 5.7?

[mistaake]

I would usually not use Denso plugs in a GM (usually my rule of thumb is ACDelco when possible or NGK in a pinch) but I have eight brand new Denso plugs floating around and saving money is always good.

Currently the vehicle has 7x Bosch Iridiums and 1x NGK Platinum. Don't ask, don't tell Do I get 7 more NGK Platinums or put these Densos in?

Use the kind that make sparks.

Rock Auto lists the Denso 4511 as a compatible replacement for the 5.7L Vortecs, which I'm assuming is what you have if your signature is accurate. Only thing I'm noticing is that they're factory gapped at .040", while most of the other options are .060". I say go for it if you've already got them laying around. Can't be much worse than the mismatched Bosch and NGKs.

All that really matters is the right seat, the right reach, and the right heat range. you can gap it to whatever you want.

By the way the only time you need twin tip plugs for wasted spark type ignitions.
