Description

The Pro Tru Street Series delivers forged construction with a coated skirt to minimize friction and wear—critical when you’re pushing boost or naturally aspirated limits. This -5cc dome configuration gives you the compression ratio control needed for tuning flexibility without sacrificing strength.
