I recently just bought an Acura 2002 3.2 TL and i was wondering . . . how often are you supposed to change the spark plugs ?

 

Change the spark plugs every 30,000 miles. Any longer and it will be a pain to get them out.

 

The spark plugs in the '02s and newer are "maintenance-free" for 105K miles. They are platinum-tipped and will last for at least that amount. Unless you do a *lot* of short-trip driving or excessive idling, there should be no need to change them before then.

 

Thanks for the facts

 

since we are talking about spark plugs...
(although not the ones on my TL).. I am already getting ready for spring time tune-up on the family minivan - '98 Pont Montana with 85k km on it-
GM has put an extended life platinum plug on this engine also, suppost to be good for 100k.. yeah right.......
So I took a quick look at the front 3 plugs 2 weeks ago.. just for the hell of it.
Well the gap was out and they needed a good cleaning. I also think its a good idea to pull them out / inspect / reinstall evry 50k just so they dont "fuse" themselfs in the head.

The same platinum tip spark plugs are also used in the 2000 TL & are not do to be change until 105,000 miles this is according to owners manual & my dealers maintenace schedule book

 

Our spark plugs may not need any changes, I'd change them out at 45,000 anyways. If you don't change them, have the dealer unscrew then, squirt some WD40 and retighten them. This is to prevent them from sticking when your car reaches 105,000 miles. A friend of mine had to have his spark plug bored out because it was stuck.
