ok so i know we dont have to change spark plugs until 100K. but im at 75 and i might as well... which one should i get ??? NGK Laser Iridium? http://www.ngksparkplugs.com/product...er_iridium.asp

or NGK Iridium IX? http://www.ngksparkplugs.com/product.../iridiumix.asp

 

and is it an easy change??? do i need to change coils as well?

 

ive gon through both n dnt really notice much of a difference n right nw im runing that bosch iridium fusion n still dnt really feel da diff.. although there is a difference on da feel of the motor with the laser ones...

ps. only reason ive gon through all the plugs is cuz i work @ autoparts store..

 

So laser would be the better one if any?

 

yes the NGK Laser Iridium is the stock plug, it has a larger center electrode and it's also coated with platinum on the side electrode, center is iridium. It lasts much longer than the thinner IX plug.

 

no you do not need to change the coil packs at all. Just remove one at a time when you do the plug, then re-install it and move onto the next plug.

Make sure to disconnect the battery before you do this work. and yes it's a very easy change. Took about 30 minutes total. If you go really slow about an hour. But you'll save a lot of $$$ from the dealer. Oh and make sure the car is COLD before you remove the plug. Aluminum heads are not that strong and taking a plug out when it's HOT could cause problems.

and I'd go with the NGK Laser Iridium plugs. That's the exact plug that is in there from the factory. Some tc's came with NGK and some came with Denso. I personally like NGK a lot better.

EDIT: If you haven't gotten yourself a spark plug socket, get one. It's not a normal socket, it has a rubber sleeve inside to hold and protect the ceramic neck of the spark plug.

 

i think mine has denso

 

alright thanks! anyone know a cheap website to order the NGK laser iridium plugs????

 

or what car part store is better to go to???

 

6.99 + tax at advanced auto parts..

29.64 total... just bout em today

 

^^ yup that's where I got mine. Sorry was late getting to this post. glad you got them. let us know how they are for you. Mine was smooth, quiet, nice.

 

yeah any ngk is about the same so its all preference but i would stick with ngk for the tc

 

will do... i'll put em in, in a few weeks, when i go home... i gotta get my cf hood clear coated etc. so then i'll stick em in + i dont have any wrenches and sockets

thanks tho!
