Hey all! Love the great feedback and advice I've gotten. Quick question pertaining to colder plugs. I have a set of Beru, one step colder plugs, and the plan is to get either a 15 or 16% pulley. My question is: Can I install the plugs before without any problems? The only driving that will be done is likely start up after oil change and driving to the shop to do the pulley, roughly 30 miles. I can wait to install after the pulley is done if need be. However, I'm waiting for my replacement Fumoto valve, and I am going to order my pulley and such today or tomorrow. The wait on my valve is like 2 weeks due to being out of stock at Out Motoring.

Thanks in advance guys.

 

Yes, install the colder plugs now.....it's not going to hurt anything.

 

so i have an 03 R53, with a reduction pulley and CAI. Ive been trying to figure what plugs would be the best to get now? I read the ones that they use in the JCW model would be the ones I want until further mods, thoughts?


thanks!!!

 

These are the ones you want as these are what we include with our pulley kit and use in our shop as they last, don't fail, or come loose like others.

You always want the colder heat range with the pulley as we see heads using stock plugs with a pulley get hairline cracks from the stock plugs

 

thanks Way! you guys have all the goodies and the right info!
