To meet the continuing needs of its customers, ATP Automotive has expanded its Graywerks line of intake manifolds. The introduction of new part numbers increases available coverage to 92 per cent of market demand. Graywerks by ATP Automotive intake manifolds meet or exceed OE specifications for performance and design so they fit right, look right and perform right the first time. All manifolds, including our injection molded intakes, come with gaskets, mounting hardware and required parts for a complete installation package. Unique to Graywerks intake manifold line is the GM 3.8L 1995-2005 application (#106001) that features an improved design, eliminating a known OE failure point.
