i just rolled over 30,000 miles with an unmodded s/c. i know i am supposed to clean off the oil inlet thing, but how often do i change the trd spark plugs? i apologize if this is already posted, but i did not find this info in a search. thx in advance.

 

Spark plugs should be good for waaay over 30k. If you want you can take the belt off, just the supercharger pulley, and see if you feel and play when you pull on the pulley or move it up and down.

 

Clean your little squirter nozzle. Check the stickied thread at the top. Bottom of the second post talks about maintenace
