Sup guys this might be mentioned already but i can't find results for it... but anyways sorry for making a useful thread if there is already one. I seen my friend's car like a long time ago he had his spark plugs changed into a aftermarket one. so i just decided to do the same today and i bought some NGK ones off of Ebay.... and then now i am really confused on the 3rd generation TL's, they need some special tools. So my main question is how do you REALLY replace it? and does it really do anything or did i just put $50 down the drain? can someone please post me a DIY for this please? lol thanks in advance.

 

It literally takes less than 5 minutes to change the spark plugs on the I4. You just need to remove the spark plug wire (it pulls straight out). Then grab a ratchet with a long extension and a 5/8" deep well socket.

If you haven't changed them in a while, it's probably a good idea to do so. A basic tune-up usually consists of new plugs, wires and a cap and rotor.

 

lol don't even have those tools.... i would buy it but when i change it the owners manual said something about 3/4 turn if too much something bad will happen if too little something bad will happen.... again do i get any horses? i doubt it but eh lol and i know it is a gain in MPG for sure? thanks

 

lol....noob
