Just got a 2004 Cayenne S. Not getting great gas mileage, going to change out the spark plugs and spark plug wires, and put in two new K&N air filters. Hoping to pick up 2-3 MPG. I have the plugs and air filters but I bought the wrong spark plug wires. Can anyone tell me what size/brand I should get? Nobody seems to know what fits where I live. Thanks...

For the 2004 M48.00 engine you need 8 x FGR6KQE spark plugs.
Porsche part number is 999 170 218 90, but I am sure that you can find them cheaper.![Wink](https://rennlist.com/forums/images/smilies/wink.gif)

Are no plug wires on the Cayenne, they're coil packs that connect directly to the plugs.
You may want to replace the coil packs (6 or 8) at the same time you replace the spark plugs, call Sunset in OR, Hennessey in Atlanta or Suncoast in FL to get the best price on the latest and greatest versions of the coil packs (don't know the latest vs. off hand).
Plenty of threads on the subject, use the search feature.
John, love the avatar, beautiful!

Coils according to the last PET update 270/27 are still the 948 602 104 05 however I believe that some newer versions exist ending with .07 to .10.

A 2-3 MPG increase in mileage would be nice... maybe you could get it up to 14 MPG!

I think I remember seeing .07 a while ago, I think mine are .05's but they were replaced some 2 yrs ago.

i was hearing and K&N are not recommended any more because they allow to much oil and debris to pass directly into the engine aside from a traditional paper filter......

Oiled air filters can ruin MAF sensors
Some will say otherwise but any oil that gets on the sensor is bad news.
The oem filters do a fine job and aftermarket filters without air box changes do nothing imo

Thanks for all the responses. I realized after more research there were no wires, just coils. Trying to decide whether to buy the coils as well and have both changed, or just not do it at all. I tried to go in and change the plugs myself but found I can't get at half the places I need to. Would cost about $200 just to have the plugs changed and I don't know if it's worth it... Any other ideas of how I might increase mileage a bit? Would plugs/coils make a noticeable difference?

Would I pay $200 for someone else to do it? No, unless time were an issue for me. But I do the majority of my own work on all my cars and have the tools and garage space to do it. But I believe $200 is reasonable for a shop charge.
