I was just wondering if anyone has any suggestions on
1. Spark plugs?? i have 25000 miles on my car and i just want to change them..
2. im changing oil and putting mobil 1 5w 20 and what kind of filter should i use?
Also if anyone has a link to magnaflow magnapacks 3in inlet 3in outlet please put it up.. i just cant find 3 inch.. but im almost certain they should make them. if not 21/2 will work. Thanks....-Chris

i wouldnt change them unless youre having problems, but id stick with NGK or motorcraft... ive had problems with autolite and alot of people in here have had problems with Bosch, at least the +4's.platinum is what they came with from the factory, but double platinum, copper, iridium have all worked fine so ive read.ive always used mobil 1 synthetic oil, and a mobil 1 filter not so much cause i noticed a difference, but why not keep the brand of oil and oil filter the same just in case.

Thanks.. im not sure what oil they used.. but ive only had the car a month.. and i figure its time to change oil... and i was just going to go ahead and replace all the little stuff. just to be on the safe side...

i wouldn't bother with doing plugs just yet unless the car was running a litttle rough buti would definitely change the oil seeing that it's used and you don't know the service history. as for the exhaust, you don't need 3" piping, the 2 1/2" piping seems to be most efficient for a N/A 2 valve
