how are they VS out stock spark plugs in performance i'm planning to get my plugs change so i need your guys opinion

 

I thought about getting these. I went to the dealer and got the OEM NGK plugs and put them in. I didn't see the need for anything but the OEM. My MAx is a 1999 daily driver with 144,xxx.

 

There is no need to use any other type of spark plug then OEM unless you are either supercharged, turbocharged or using nitrous. The factory ignition system is more then adaquite for stock cylinder pressures. You are not going to see any HP improvements by flip flopping between spark plug brands. However your vehicle may feel stronger simply because there is a new set of plugs installed. i hope that helps you with your decision.

 

thanks for the replys guys

 

I heard you get more performance from copper plugs plus they're only 10 bucks a whole set.
