Denso sparkplugs - Focaljet

**Terrible1** · 03-23-2006, 12:57 PM

Are they really worth being 4X the amount of an autolite or motorcraft??? Powerworks tells me I need the stock SVT plug for my sc car. What have been your experience with these??

I would not recommend using stock plugs on the car when it is making much more hp than stock. We use the denso spark plugs on the shops supercharged car. Our customers have used denso plugs on turbo and supercharger cars with good results. One customer with a turbo car noted that the denso spark plugs lasted much longer than the motorcraft copper plugs he was using before.

I've got a powerworks supercharger and it came with 1 stage colder plugs ( stock svt is what I was told by them ) and I was just lookin to replace them this spring. Are the denso's really worth the $$$ cause if not I'll just get some autolite's or something comparable???

The motorcraft spark plugs are not that expensive. They will not last as long compared to the denso spark plugs. We have customers that have used this on turboed, supercharged, and nitrous cars. http://focus.c-f-m.com/index.asp?Pag...ROD&ProdID=371
