silvermistLS Posted June 18, 2008 Share Posted June 18, 2008 Hey guys, I'm thinking of replacing my sparkplugs since my car is just about to hit 120K miles. Do you guys know where to get them? Are the original iridium plugs? I can go to the dealer, but would appreciate it if you guys know of online stores and or prices...

ko90ls Posted June 18, 2008 Share Posted June 18, 2008 original is denso platinum. Iridium is better. I used Sparkplugs.com for the best pricing Quote Link to comment Share on other sites More sharing options...
chilkoot Posted June 18, 2008 Share Posted June 18, 2008 I replaced with NGK Iridiums, supposedly identical to stock and you can get them at Advance. They work very well, worth every penny. At that age I would suggest wires too, but make sure to use OEM. Quote Link to comment Share on other sites More sharing options...
jcrome04 Posted June 18, 2008 Share Posted June 18, 2008 OEM wires, and NGM Iridium IX plugs from sparkplugs.com! Make sure you torque them down proper. Use some dielectric grease, and anti-seize. I didn't torque/grease/seize my plugs when I first replaced them, So I started from scratch and got new plugs and a torque wrench. By my seat of the pants guesstimate the difference was amazing, felt a lot more solid. Quote Link to comment Share on other sites More sharing options...

Lexusfreak Posted June 18, 2008 Share Posted June 18, 2008 I would go with the Denso Iridium long life SK20R11 plugs personally with .044" gap....the NGK IX plugs are very good, but will only last roughly 30 - 40k miles. Just my 2 cents. Quote Link to comment Share on other sites More sharing options...
