Hey All do you know what type of Sparkplugs we have in our cars. I was wondering if we could get any small gains with a switch to Denso Irridium Plugs. They are said to be the best out there and they did wonders for my 99

Thanks
Dave

 

Not really sure about the applicability, but I always heard that going with copper plugs will offer better performance than the stock platinums. But this was for my supercharged engine. The advice I got time and again, was to go with a "colder" rated plug, that was copper. Most people I've talked to, said that the irridium plugs offered longevity, not performance. But this was like 2 years ago. If you do switch to copper, you need to replace the plugs more often tho.

 

What are you going to get with Denso plugs.....1/2 hp or something like that...you will NEVER feel it driving the car. Save your money!!!!!!!, Denso is a bunch of hype!!!!!!!
