spark plug changed after 22k mi
Just want to share my thoughts on spark plugs:
My car was getting poorer mileage (17-18 mpg instead of 19-20 w/ mostly hiway). It actually stalled a few times while sitting in traffic too.
I changed the plugs at 22k mi. They look brown and was darker than the last time I had replaced them at 15k mi. I think I will change the plugs every 15-20k mi going forward.
The job took me 1.5 hrs from bottom and top of the car. You need a 21MM deep socket to get the plugs out. I bought a little die electric grease and anti sieze lube also. It now runs very smoothly and the time was well spent.

Last time I changed mine, it only took about 15-20 minutes. And I did it from the top. All you need is a long extension (18") and a swivel socket or universal swivel adapter. Bada Bing Baby!
BTW: I try to change mine every 6K miles.

When my car was stock, the plugs lasted about 30K.
Once I started adding PFC, M2 larger, dp, mp and 13 psi, they last about 10K.
With the HKS TwinSparks, it's less than 10K. I put a brand new set in and about 3K later, it looked like it had 10K on it. Car ran better though. Havent' had time to dyno the car yet.

I got 15k miles out of the last set of plugs but they really should have been changed before then. IMO, plugs are about 10-12k miles in these cars. I switched to all 9s last time, so we'll see if that improves the durability.

I can change the plugs in my car in record time...but changing plugs in a stock car(P/S and A/C equipped)...gee christ that sucker's a PITA from the top. Easy as pie from underneath though.
FWIW, I change my plugs every 6 MONTHS. The last set of plugs went thru 3 or 4 engine REBUILDS. All about the tuning!

I did mine without removing anything. I don't know about 15/16 socket but the 21 MM socket worked fine for me. Mine is pretty much stock so 20k mi is my plan. Local rotary shops recommend every 15k mi though.
I don't know how you can do your plugs in 15 min. It takes me that long to change plugs on a v6 that has the plugs in plain view. Time yourself with a stop watch next time...
