Just finished Spark plugs.

Well, I think I overpaid. I really see no difference from the stock plugs that were in there for 60k miles. I used ndk on my bikes for years and liked what I read about iridium holding up, so I thought I would give them a try. I think I could have went with champion and had the same results though. I plan on pulling the plugs to see how they have held up and as a pre-emptive maintenance.

Thanks for the guide. I just finished mine, and it was no big deal. I think it took me two hours.

BTW, I got my plug tube puller tool (boat drain plug) from Cabela's for $4.

Couple of questions. Mike: Did the transom plug (boat drain plug) work well for you? (I have read some posts where people seemed to think they weren’t that effective.) How many miles do you have on your Boxster, and did the tubes seem to be in good shape? Pretty easy to get out?

Also (for anyone to answer): How are the cylinders numbered? I thought I read somewhere (I can’t find it again…don’t you just HATE that??) that 1-3 were on the passenger side (1 being right behind the passenger seat, 3 being at the rear end of the engine) and 4-6 being similar on the driver’s side (4 right behind the driver, 6 at the rear end). Is that right? (I ask because I got a “cylinder 1 misfire” CEL recently.)

Bump.

Wow, is it possible NOBODY knows what the cylinder numbering scheme is for these cars is?

[mptoledo]

Sorry, everybody must be out enjoying the car(like me). I really don't know the answer to that question. You might want to start a new thread in the main to get more looks.

I have a shop manual that says you have the cylinder numbering correct. Standing at the rear of the vehicle and looking forward, odd on the right (1,3,5 from front to back) even on the left (2,4,6).
