I just got a set of bosch Ir fusion spark plugs for free at the local auto parts store. (I won a contest and I got spark plugs, yay) I'm just wondering if anyone has run these plugs in their car? How did they work? I usually run NGK plugs but these were free and I feel like installing them. Any thoughts?

 

Anyone?

 

A good amount of people run the Bosch +4's in their Mini's and have no complaints, only good experiences. The Ir Fusions are only a higher grade plug so I'd say go for it. I work auto parts retail and they sell for anything from $8-10 each.

 

Cool deal. I will be installing them soon then!
