I run Bosch +4's I noticed a difference in Acceleration over the NGK's I had (Not to step on toes but I hate NGK's due to bad luck with em)

All my vehicles have been on Bosh Plat plugs and never had a problems and they last a long time. The vette was the first time I ever used the +4's and I sure like em.

Only thing though IF you ever plan to run nitrous DON'T use a Plat plug of any brand. The plat flakes away from the nitrous.

I run AC delco's

And have been happy with em.. I had split fires in em for a bit... really no diff!


Vig!

Same here! They're quite costly at $6.00 a plug, but you can really notice a smoother running car.

+ 4's here in the 84 CF and 91 ZR-1 can't honestly say I noticed any power increase in either vehicle but they both fire right off at -10 below zero in the winter. 84 CF 91 ZR-1
