which plugs are you going to replace with?

Hello all,

I recently replaced my at 65K miles with NGK Iridium. It is run perfect now.
Prior to changing it out, the CEL comes on with fail code P0300 with engine number 1,5,6 misfire.

I got the plug from Pepboy auto part for $7 per each.
my car is also a 2K3 TL/s

English?

You can replace them with NGK iridiums or Denos Iridiums.

Can anyone name any they prefer or would like to recommend?

money may or may not be an object, so if its expensive, say it anyways

Stick with teh oem plug. You wont gain any thing from any other plug, plus they last teh longest. There is really no need to change them before 100k unless your getting a cel

i put in bosch or ngk double platinums.... i forgot which one they were, but they guy told me they were the ones that were meant for the car... i heard the difference wasn't really noticable going from double platinum to iridium, so basically a waste of money for minor if any gains...

You're gonna be paying for new coils. Use what the car came with stock, not like you replace them every 3k, don't be cheap.

disgookonfiya

the ones i bought were what the car uses stock... i'm not being cheap, the car does not come with iridiums from the factory buddy, they have double platinum spark plugs...

Really? when you replaced the stock ones they were platinum? I thought CL/TLs came with iridium plugs...

disgookonfiya

yup, i believe they come stock with NGK double platinum spark plugs, i can't think of one car that comes from the factory with iridium plugs....

i have a 2000 TL3.2 I have stock spark plugs, what kind you guys recommend for me to replace then with.?

69tl

wondering does anybody know the link of where they got it and which type of spark plug

2000tl32

Now this is weird?

i replaced my spark plugs at 127k. With the old spark plugs I was getting 370 miles per tank. Now with the new spark plug, I am getting 320 miles per tank....wtf

I used NGK laser part number (PZFR5F-11) from this store(http://risingsunimportparts.com/pages/)


Can someone tell me what is going on with my MPG.

thanks
