For the first time in 7 years I think I may be switching back to NGK from my current TorqueMaster plugs. I think I am on my 3rd set of TM's as I feel that they lose their performance and life relatively quick.

I am now looking into the NGK Iridium IX. Can anyone else recommend a spark plug with great performance and great quality? I really don't want to spend more than $10 per plug though.

Thanks!

I use OEM Iridium Denso. In theory, all the spark plug does is provide ground for the secondary ignition system. I dont see whats the point of buying expensive brands. Just stick with oem specs. If u are a spirited driver, u can get colder heat range spark plugs.

I have NGK Iridium's in my RX300. Basically OE equipment.

idont think you need cooler plugs unless youre boosted no?

I run NGK Iridium... watever same spec as stock.

on boosted i run the same NGK Iridums but different gap... a cooler plug.

Iridium IX's have an Iridium tip with a copper ground. Hence, those IX's won't last as long as advertised. The plugs that I'm running have Iridium tips with a platinum ground, good for well over 100k.
