well after seeing how much of a pain in the *** it would be to replace em myself, my dad knows a guy who does tune ups with new spark plugs for $75 (and thats the 8cyl price lol)

truck seems a little bit peppier ... ill let you guys know if my gas miles go up cause thats what im hoping for ... i didnt get to see the old ones so im not sure how fouled they may have been

 

on a 2.5? cant be that hard, just do it yourself bud.

 

already did it and the engine is dual spark ... so thats 8 plugs .... and without a special tool to get to the drivers side rear one you have to take the intake manifold off

 

i got at all mine with out removing the Mani. one thing I did was unbolt the a/c and move it some to make things roomier, but it's not impossible to change them all without takeing anything else off if you've got the patience. and a long peice of fuel hose makes getting them started alot easier.

 

I've done it with the intake off before. Wasn't fun but with the right tools its not 2 bad.

 

i dont have the paitence and the shop got it done in 1 hr lot faster than it woulda took me

 

i got all mine replaced without taking off the intake manifold or the AC unit. it does take alot of patience and busted knuckles but i got it done. not in one hour though it took me around 3 hours to complete

 

so far no noticable increase in gas miles, but was going pretty fast last freeway trip .... i only got 20 mpg and my girl who was following me only got 26 mpg out of her 02 hyundai accent haha
