Hardin Marine Flame Arrestors

They start with the finest 60661-T6 billet aluminum and CNC machine it to perfection.  Each unit is then hand polished by their experienced master craftsmen to a mirror finish.  The assembly is then mated with a 3" tall high-flow, multi-layered stainless steel screened element. The top and bottom sections rest solidly on unique stand-offs which will not allow the element to be crushed as can happen with common filter elements.

Whether you need standard or a custom dimension, each arrestor is built to exacting specifications. There are no sloppy adjustable mounting bases or elongated holes to contend with, just pure perfection.

Available for single or dual carburetor applications to fit most popular Barry Grant, Holley and Edelbrock carburetors. Need a custom center to center dimension....NO PROBLEM, just give us a call at 800-225-9871 for a quote.

Available anodized, powder coated, and/or private labeled with your logo.

This new oval billet style flame arrestor is perfect for someone looking for a modern oval style flame arrestor at an affordable price. The highly polished base and top sandwich a K & N flame arrestor in a sleek and compact package 12" long by 8-1/2" wide. Available only in the popular 5-1/8" inlet single carburetor application.

Hardin Marine and K&N have teamed up to bring you an affordable entry level performance filter/flame arrestor kit. Air intake to bolt directly to your Mercury Magnum series engines throttle body. The expanding shape of this intake assures increased air speed, something that block like aluminum adapters can't do. Then just clamp on the K&N flame arrestor and you're ready to go.

Note: These clamp-on filter/flame arrestors have limitations to their air flow. These elements are only able to support enough air flow for around 485 horsepower, after that they become restrictive.

Well here's what you get when Hardin Marine pulls out all the stops to design a flame arrestor with the most airflow possible for MerCruiser's Magnum MPI Series engines. Sure a number of companies claim to make ultra hi-flow units, let's compare the facts.

Size of this unit measures 11-1/2" long, 6" tall by a full 4-5/8" thick, no other MPI series flame arrestor comes close. This unit flows as much as 300 CFM more than clamp-on series flame arrestors. So you wonder how do they get such a large flame arrestor in the limited space available? By simply slightly offsetting the assembly towards the front of the engine Hardin Marine has been able to allow clearance of aftermarket performance exhaust systems, a feature that has plagued other brands. But the best is yet to come, you see the Hardin Marine "XS" flame arrestor is mated to 1-1/2" thick dyno proven throttle body spacer that's shown to increase horsepower and torque from 2000 rpm on up where you need it most.

All of this in a beautifully polished finish and this unit attaches with all factory hardware just like the original. But best of all it's US Coast Guard approved. If you want the ultimate MPI flame arrestor the Hardin Marine "XS" unit is the one to demand.

The only way to maintain peek performance from your flame arrester. This simple kit comes with filter cleaner and pre-oil. Some simple filter service will keep your engine at peak performance.
