I am in the process of buying new spark plugs for my 2003 TL and was told by 2 different online company's that Denso Iridium plugs are better then NGK from both a performance and quality standpoint. That also come with a better warranty.

Agree or disagree?

Thanks

Thanks that does help me with my decision

 

NGK will far outlast the Densos. Ive run the Denso before and seen NO improvement whatsoever and had to replace them after 40k

 

I found NGK's for 7.00 a plug at sparkplugs.com. That sounds like a good deal, but wanted to see if you knew of a cheaper place. Possibly one of our vendors?

 

You can buy NGK Iridium for that anywhere in your town. Call Kragen or similar

 

pepboys wanted 14.99 per plug and autozone 13.99. Dont have any Kragens
