Your choices on spark plugs are limited on the rx-8
either the stock ones or the RX-7's plugs. The RX-7 ones are cheaper and some members here use them without any issues. If your car is still under warranty I would stick with stock plugs. You can find them for $20.00 each at http://www.sparkplugs.com/

 

Nope - stick with stock - a spark plug ain't gonna do it.

what would the benefits be with using rx-7 spark plugs? i don't see any. they would prolly run higher ohms and have worst flame propa...

for best ignition performance, you want everything to fire with the lowest resistance...so i would recommend just saving some money and getting some cheap magnecor 10mm wires. leave the stock plat plugs alone.

 

i believe the 7 plugs are colder, and they are cheaper

 

Go to www.autopartswarehouse.com for all 4 spark plugs are like 85 dollars and free shipping

 

or you could go here

 

yeah but why pay 109 plus shipping when you can get them for 85

 

true. thats just where i bought them

 

DO NOT USE RX-7 PLUGS IN THE LEADING POSITIONS!!!

The only reason to use rx7 plugs would be to save money. They are 2mm longer so you will need to shim the plug.

 

There are a few people who have tried Denso's. Only one has said they are great.

The others never responded to my Emails.

 

Don't forget Napa Auto Parts for about $23 each before tax. Be sure to call your local Napa to find out which store has them because most don't. They will search on their computer to find which store has them, which will probably be the local region distribution center. If it's too far from you, they will ship them to the store that is closest to you on the same day! Of course this is if you can't wait for mail-ordering.
