Hi guys, sorry to bother you again with Spark plugs... i did some research and its never clear enough to me...

so my seven is running little mods such as intake, catback and BOV... nothing else atm

so im looking for the best spark plug money can buy me. HKS? NGK? Denso?

thanks for your help!

 

Run the stock NGK's 7s and 9s.

BUR9EQ, BUR7EQ.

 

+1, change them around every 15k.. So about every 2 years depending on how often you drive the car

 

Alright thank you very much for the quick reply guys!

oh while we're at it... should i buy a new wire set as well?

 

Wouldn't hurt. Do it once and you wont have to worry

 

/thread hijack/

anyone know of a good site to order bulk ngk 10.5s from?

/end hijack/

and after a few more boltons, you should prolly start running 9's in both. and new wires never hurt. go for it.

 

I usually get that stuff from Mazdatrix or rx7.com. Sometimes you can find them cheaper on other sites if you look hard enough.

 

you can bulk order at autozone also

 

Autozone wants to charge me 13 bucks for non plats. And they dont have it in stock.

If you wanna bulk order, go to sparkplugs.com

8 bucks for plat and 7 for non plats.
