Give your engine the sparks she needs!

 

More in stock!

 

Got some more in, PM to get yours today!

 

PMs replied! They will not fit the VIIIs.

 

question, at what mileage interval is it recommended these be replaced? they are going in for my meth tune next weekend, and i want to plan ahead to have another set on hand when they need replacing..thanks guys!

 

Hello
Denso recommends them changed at 30k. On their site they say that iridium
can last up to 120K miles! But due to different condition, high boost, leaner AFRs, ect
They recommend 30k. I've had mine for about 5k Miles so far and everything seems perfect.

 

thanks for the reply!

 

No problem.
We still have a couple sets left in stock!

 

Got more in stock, shoot us a PM!

 

Make sure you got fresh plugs ready for your IX!

 

Did anyones stock plugs break when they took them out or are these isolated "jackass" incidents?

 

Usually they don't break when you take them out. You want the engine to be cool, and hopefully it wasn't torqued on there too tight.

 

Still in stock!

 

When are these needed? I pulled my stock IX plugs last weekend, and they had the perfect tan color. I've got a mail-in flash on an otherwise stock motor. I'm thinking that if anything, I might try the Denso Iridium in the stock heat range.
