You know why?? Cause it is not "PFR5G", it should be "PFR5G-11". IT is NGK's Laser Platinum plug, also the orginal equipment that come with the car when new. You can get those at kragen, but they are 18 bucks a pop, not cheap but they'll last yo a long time. Now you have the part #, look around for a better price.j30WAY wrote: I've browsed the web and haven't been able to find any NGK PFR5G that are specified for a J30.
Not really any performance differences. The plats will just last longer.j30WAY wrote:oh Btw i found the PFR5G-11 plugs for 8.25 each, but i dunno still seems kinda expensive. Is there really gonna be a world of difference betwen 2 dollar and 8 dollar plugs?
