Hey guys, sorry for a stupid question, but 8 am posting from my phone and I can't search too easily

I'm chipped, 2002 180 FWD. Gap should be at .28, what is the plug code that I should get? I'm at the store now! thx

 

I had the same question kind of, becasue Im chipped and going to be running morePsi. here soon with the BM, shouldnt I go with colder plugs? Which ones and what gap. Thanks

 

NGK PFR6Q or Denso IK20 gapped to 0.29.

You need to go to colder plugs gapped at 0.28 once you are more than 50HP over stock.

XCLR8TT, I am more than 50 over stock, soon to be a lot more. Should I go with the pfr6q?

Should I change the gap to .28 myself? Thanks!

 

You should probably go to a colder plug than the stock PF6RQ. Yes, you should gap the plugs, they come out of the box at around 0.35. Make sure you get a disk-type gap gauge, not the wire type. I personally run IK22 Iridiums gapped at 0.29.

 

just get the NGK BKR7E. One heat range colder and gapped. to .028 will due nice. Plus they are only a couple of bucks and will go every other oil change.

 

Due to advice from my local dealer(70 miles away) I changed to the new Bosch Fusion plugs that are both platinum and Iridium with a 0.28 gap and am duely impressed. Another benefit is that you fon't have to order them like Denso's as they are available at any Auto zone for $17 a piece

 

why would you pay $17 a peice for a plug? The ngk's are about $1.50 a peice and work great. Then just change them about every 15k miles.
