I thought the change interval was 50k.

 

Anywhere to get a good deal online for OEM plugs or so I have to go get ripped off at pep boys/advance auto/(input name here)..??

 

clubplug.net

 

so, have anyone tried Pulstar?

They're crap, don't work any better than the typical single-electrode plugs.

One of the tuner mags did a test and showed the difference to be well within the dyno margin of error.

 

thanks alot i was about to waste 100 bux

 

^copper electrodes make more power than plats.

copper electrodes need to be swapped out much more frequently.

on the SS I woujld change the plugs every oil change.

on the S2000, I have two sets..a dirty set to use when seafoaming, and a clean set that i run. This also helps the block and plug NOT weld together..

 

ok well i'm definitely gonna change my plugs in spring, mightaswell...won't do any harm.

 

I was told the Bosch Iridium 4 prongs can last for 100Km

 

O....E.....M......
