Im trying to buy some spark plug for my car. i been looking at carparts.com and they have some NGK Iridium for like 3.04 a piece but they also have one that saids OE style iridium plugs. whats the difference between these 2????

 

NGK or Denso????

 

SC300 or SC400? Boosted or NA?

 

..make sure they come pre-gapped

 

SC400 do you guys have any good sites where i can buy them from for a good price???

 

good place call napa.

why pay for shipping?

 

jegs.com is where i get my plugs

 

I remember seeing NGK 3330's for fairly cheap on www.horsepowerfreaks.com i believe....somehwere around $2.xx per plug. So, maybe try looking on that website for the other spark plugs.

 

Which is the best dyno proven plug for an SC400?
please add plug number.
