Flame arrestors are required by law for every boat using a gasoline engine. A properly sized flame arrestor is crucial for maximum performance--too small and it will restrict engine breathing. This Holley Marine flame arrestor is designed to protect your vessel from the potentially disastrous effects of backfire--plus it looks great!

Holley's products include performance fuel pumps, fuel injection, intake manifolds, cylinder heads & engine dress?up products for street performance, race and marine applications. As a single solution, or partnered with products from other Holley companies, Hooker Headers, Flowtech Headers, NOS, Weiand, or Earl's, Holley products can give you the edge you need over the competition.
