As title says the tuner I'm going with recommended ngk's 5141's. As far as Ive read most run ngk 4177's. 4177 are copper and 5141 platinums. Im pretty much stock and not going more than 7-8lbs at most just want be have a safe tune. Tuner is well known for tuning around here just wasn't sure on the plugs he recommended because from what Im reading platinums are not good with boost. Any thoughts would be appreciated. Thanks
