Revolution Performance

M-8 Replacement 55 mm Intake Manifold

Recent new products from Plymouth, Wisconsin based Revolution Performance include this 55 mm intake manifold for 2017-2023 M-8 applications - described as the "ultimate cost-effective upgrade," says Chief Sales Manager Jeff Meyer.

"High flow means extra horsepower and torque just by bolting on our manifold." Replacing the stock plastic design with the company's precision CNC-machined 356 T6 heat-treated cast aluminum design will, on average, "boost your Harley's performance by a remarkable 3-4% horsepower/torque by just bolting on our manifold. Pair our manifold with a simple tune and see 5-6% horsepower/torque gain. 

"Add our CNC ported cylinder head package with the manifold and tune to see 12-14% horsepower/torque increase. A simple and affordable way to gain performance!"

Available in choice of wrinkle black powder-coat or a vapor-blasted natural corrosion resistant finishes, this replacement manifold is ported for optimum performance - "we've gone the extra mile to ensure maximum performance gains. Our intake manifold is expertly ported to deliver optimum airflow and unleash the true potential of your Milwaukee-8 engine."

The specifications are 55 mm with 1.9 inch intake runners and fits all 2017-2023 M-8 models except the new 2023 CVO VVT 121" engine.
