I am selling 4 Denzo ITV22 step colder plugs for the mazdaspeed 3/6. They were used for ~1500 miles. I never got the downpipe, front mount and all the other things I had planned on so dont need the colder range. These sell for $12 a piece and are yours for $25USD shipped. Prefered method of payment is paypal for both of our safety. Thanks!
