SPARK PLUG GAP

[hahnmgh63]

Mbagge01, which NGK plug are you using? Looking at the NGK heat range chart they should probably BKR7EIX which compares to the stock BERU in heat range.

hahnmgh63, I have been using BKR6EIX which I thought is heat range 6, and the same heat range as stock beru. I was going to switch to BKR7EIX which is heat range 7 and one step colder than stock, or am I wrong? Maybe that is my problem

For Japanese plugs, the higher the number the colder the range is. For European plugs, the higher the number the hotter the range is.The heat/cold range are opposite of each other, some caution is recommendable.

The gap on the NGK spark plugs is .032. I have read some posts about decreasing the gap to .025 for tuned porsches. Does anyone have an opinion on gapping for a tuned cayenne. Would going one heat range colder be enough or should I also decrease the gap. I would be interested if anyone has a EVOM tune and did adjustments in the spark plugs.

HELLO CAN ANYONE TELL ME THE GAP SPECS FOR A Denso Iridium Spark Plug FOR A PORSCHE CAYENNE TURBO 2004. tHANKS DEAN

Loren said both the turbo and the NA V8 4.5L use the same gap. I don't think that is correct. Turbo is 0.8 (single electrode) and NA is 1.6 (multi-electrode). I sure wonder why they are different but that's for another discussion. 🤓🤓I also read somewhere that they are pre-gapped and just put my previous ones in the way they were. Didn't check. They were NGK iridium and the center electrodes melted off. Their literature says the ground electrode will fail before the center one does. Turns out that's not the case! So I'm going to try out the autolite double platinum. Close to OE for turbo. They say they use double platinum in OE anyway. Checked the gap for 0.8 (Turbo) and they were way larger. So I set them. Thanks for all the info on here!

You are correct - it changed in 2009 and I missed it.

How about the 4.5 cayenne s? Does anyone know the gap for those plugs? I've seen some on ebay and they say 'gap: 1' but I don't trust the listing as I cannot find confirmation online.

Thanks in advance

I bought platinum Denso TT for my Porsche Cayenne S 2006 V8 4.5 and I would like to know if these plugs are pre set for changing out?

We always re-gap the Denso TT plugs to 1.6 mm using a special tool:
