Denso Power Iridium Racing Spark Plugs
 

Includes 2 Leading And 2 Trailing Plugs

These are plugs I bought a few months back, put them on, used them for about 2kmiles roughly. So these are practically new. They really add a noticeable difference in the acceleration of my 8. But I decided I want everything back to stock, all genuine mazda parts only. They will come shipped in a Mazda OEM spark plug box since I dont have the original boxes. These plugs are not cheap for a full set online so your getting a pretty sweet deal. Denso claims around 5-9mpg improvement on fuel. I personally seen about 2-3. At least its an improvement.

Shipping is free. I can accept paypal for those of you who are not local. If you are local to tampa-orlando-sarasota you can always come pick them up or meet up.

Sorry you wasted your money.

The OEM plugs are the best plugs to use for all N/A engines. Period.

Any improvement you felt was simply a pickup over old and failing OEM plugs.

OEM plugs are at worst equal to these, and are $80 for all 4 brand new.

Price Reduced. $50.00

what site sells them 4 for $80? doubt it would be the dealership. im going to be needing some new ones soon.
