Might be a dumb question but I picked up colder spark plugs to install on my car with the intention of doing so after installing my 15% pulley. Due to my stock pulley giving me a hard time and my garage issue at the moment, I'm forced to wait a few months before installing my pulley. My car hit the 80k mark this week and I'm not entirely sure when the spark plugs were replaced so I'm thinking of replacing it.

Question is, would it be an issue upgrading to colder spark plugs given that my only modification right now is my DDM CAI?

 

FWIW I think you'd be fine running colder plugs in your MINI. Once you get that pulley on you'll be >

 

Thanks Crashton. Yeah, I can't wait to install the pulley and get a tune after. I tried to install my pulley at my friend's garage while they were out of town and tore everything down but got bogged down by the stock pulley not wanting to come out.

 

You'll be fine with them on a mostly stock car. I had them on my car before i did my pulley just for a day, it acctually drove really nice that way. Anything is gonna be better than old worn out plugs. just make sure you torque them down to spec.
