Hi guys, i'm going to be changing my plugs in about 1500 mi. I was looking at the following NGK spark plugs:

the OE Style Laser Platinum; PFR5G-11

and:
the Iridium IX Plug; BKR5EIX-11
http://www.partsamerica.com/ProductD...pe=960&ptset=A

I've been to NGK's website and it seems that the PFR5G's are the "stock" ones. Which are better in terms of performance/efficiency?

 

i usually get PFRG-11s....they are stock....some u NGK coppers and just change them more often....its really personal preference but i stick with what came stock

 

ok, sounds good i'll get the platinums then

 

I'f your going to use NGK PFR5G-11, get them from Courtesy Parts.com
$57.00 for 6-pac

 

get the platinums, they're the stock plugs. In my experience, they're better than the iridiums.

 

what's the verdict on BKR5EGP? I bought a set to install tomorrow....

 

Those will assault your piston....Too long...

 

Thanks guys, i really appreciate your comments!!

NmexMAX, what do you suggest?

 

Bkr5e-11....

 

oh..the Iridium ones. How come most people still reccommend platinums though?

 

If those are too long, how come my car has been running those for the past 100,xxx miles? I bought them from Courtesy too.

 

I think he's talking about the BKR5EGP plugs.

The PFR5G-11 are the stock ones.

 

we're talking about the PFR5G-11 and the BKR5EIX-11

I'm leaning more towards the PFR5G-11, unless the BKR5EIX-11 are better

 

REALLY? Hmmm...Isn't it misleading then that most stores have those as a replacement for the car? They're even listed on the NGK Website.....
