I can assure you that is false info. I am a assistant Manager for PepBoys and we have not had any recall for any plugs.


Also eralier someone mentioned some new plugs. Bosh has a new plug called the IR FUSSION.

--fused Iridium/Platinum core --- reaches operatin temp faster than other plugs
--Foiur yttrium enhanced electrodes -- resist wear better
-- less voltage required over the life of plug -- longer life.

But the downfall is they are $10 apeice. Right now Pepboys does not carry them but I'm sure in the futer we will.

 

I snagged some +4's today...haven't really taken the car out and about too much yet...but i noticed a smoother idle. Not sure if plugs would have anything to do with it, or if i was just imagining the whole thing.

 

are spark plugs worth it for every 2.4 owner? i have an auto and only performance mod is intake.

 

I'm in the same boat. Represent!

 

i'm also an auto...i noticed the car gives me a little bit more power when i want it at the low end...not a ton, obviously. I mean for $30 bucks and a 20 min install? Why not?

 

so it wont be a harmful thing to do?

 

I just installed these plugs in my 2.2 LS and it did make a little difference in acceleration. Nothing huge, but as said before, it's worth $30.

 

Do any of you know how much better if at all the new Fusion plugs are compared to the +4's?? Just want to know before I purchase the +4's if the Fusions are better, I will get them. They are 2 dollars a plug more than the +4's are also.

 

Platinum conducts electricity better than iridium so the +4's may have a hotter spark. In theory, Iridium should make the plugs last longer. I think you'll see better plug life out of the Fusions, but the best you can hope for is identical performance. BTW, copper has the best conductivity, so it generates the hottest spark, but it is soft and needs changing often for best performance. I think slipping in some fresh copper NGKs on track day is best for max. plug pefrormance. Just change them to platinum or iridium for the street.
