The shop wanted to charge me $13.00 per plug and $28.00 per plug installation. Just the plugs! The coil packs were priced separately for parts and installation. Heck, I may not even need a tune...I get 19.4mpg city and 23.8 hwy in FT 4WD.
Yea i used nkg plugs as recommended on this forum they were only $3 each and i didnt change my coil packs but priced them out at around $30 ea at the local auto parts store amazon has a six pack with spark plugs for $100 i could not imagine spending they much on something that cost me $20 to do myself and i am in no way a mechanic but its a really easy job get a 5/8 spark plug socket and some different length extensions makes it easier
