i don't know, for some reason i feel like my car grumbles a little more than before when i get on it (kind of like it might be mis-firing).
i was just wondering if any of you changed out your plugs (not that you were experiencing the same thing). and if so, what kind did you go with and how many miles were on the clock? i just thought maybe it would smoothen things out a bit.

thanx,

denso iridiums at 40k

 

ok i was thinking the same thing because i actually just hit 40k.

thanx,

Can I use NGK iridium for my NA G coupe?

 

yes.

 

Those work just fine. I have those.

 

I am at 42K and have been thinking about doing this aswell looks like it is gonna be something do to this weekend

 

What's the part number for the NGK Iridium? Any one notice a performance difference with them?

TIA

 

LFR5AIX-11 and no I noticed no performance difference... did mine at 30K foir the helluvit - wouldn't bother to be honest.

 

Spark plugs usually are toast by the time you reach 60k miles.

The harder you push your car, the faster they will expire.
I had mine swapped out and was shocked how bad they were.

Felt a difference immediately but i did have more than 30k miles when they were swapped.

I guess with 90k, it's time I do mine, huh? Lol I'll order them up today....

 

Thanks. I've heard varying opinions on whether a change in plugs is noticeable or not. I've always been on the look-out for placebo effects.

I'd probably change them out anyway, if they were easier to get to. I may as well wait until it's closer to scheduled change.

 

changed them at 36k with Iridium IX Sparkplugs, it was not in as bad condition as i thought they would be.

 

Pulled these out yesterday, 91,000 on them. I guess it's safe to say it was about time.....

 

holy crap! those looked like mine at 75k! makes a difference now huh
