which spark plug would be the best to get for and 2003 tl-s with some mods. cause im planing on doing a full maintenance, and would like to know thank you.

 

The stock NGK plug

 

wow...u could have searched for this and gotten the answer much quicker lol

 

NGK Iridium or Iridium IX (racer version) of the correct heat range for a type S stock is a good start
Then do plug checks to see if that heat is good with the fuel/air/exhaust mix
Plugs tell you right away if the engine is happy

May need a step colder for long high speed trips or hotter plug for other uses

 

as said above NGK Iridium IX is where its at. they are $7 a piece at autozone or local auto parts store, coming to a total of $42 for all six spark plugs.

i also made a do-it-yourself (DIY) to help anyone that wants to learn the ins and outs of changing the spark plugs on our cars.

have fun and if you do them. the rear passenger side spark plug is hard to remove but a breeze to put the new one back in!

 

x3 on the NGK Iridium IX. Easy DIY too.

 

@bonknhead

Was the first rear passenger side spark plug removal easy? XD

its easy if you use a 3 and 6 inch extension on the plug socket- lowering down sections
There is even a bump out on the firewall for your hand!

 

It was probably the toughest to get to, but still not too bad. It took me about 30-45 minutes for me to replace all six plugs 2 1/2 years ago at 80k.

 

it took me an hour considering it was my first time trying it out.

and 01tl4tl i know the trick of using the 3" and 6" extension. you told me that and i replaced my spark plugs a few weeks ago

 

good!
just passing the info out again when I see the question- for the ziners at large reading this

 

Long reach plug socket works even better, IMO.

 

Its very easy, spark plug change on these cars is a 20 min job on the TL-P 25 min on the TL-S (its easiest to remove the 2 bolts that hold the IMRC on and move it out of the way which takes the additional 5 min). I could probably get the garage cleanup in that time as well.

 

Very easy change, I bought the NGK Iridium IX plugs and noticed a huge difference after the change out.

 

im on this fast !!!
