Velocity Stack- Billet/ HP StackWhat is a Velocity stack? A velocity stack in this instance, is a bolt on enhancement that fastens to your air cleaner base and is able to produce low end torque and faster throttle response. But how? Simple the faster and straighter you can deliver air into the carburetor before it reaches the boosters, 2 things will happen. Forcing the air to speed up will create a better and fuller intake charge, creating almost a " turbo like effect". Faster air

What is a Velocity stack? A velocity stack in this instance, is a bolt on enhancement that fastens to your air cleaner base and is able to produce low end torque and faster throttle response.

But how? Simple... the faster and straighter you can deliver air into the carburetor before it reaches the boosters, 2 things will happen.

  1. Forcing the air to speed up will create a better and fuller intake charge, creating almost a " turbo like effect".
  2. Faster air/fuel delivery, which creates a quicker throttle response and a definite on-track feel difference. 

Our dyno testing, and racing feedback from customers/drivers had been nothing short of amazing. We look forward to hearing about and seeing all of the success that our velocity stacks are able to bring you!

MerCruiser Replacement Parts
OEM quality MerCruiser Alpha 1 Gen1 replacement part. Everything you need and some things you don't because it's a universal kit that works for several models.

OEM is always the answer
No reason not to go OEM for this! Came with every possible gasket and seal I could need. Specifically for my Alpha One Gen 1 it took maybe 25-30 min to completely install. While you’re there check the base plate for wear and the other surrounding items like your water tube. Rather keep the lower unit off for an extra day to get another part than a catastrophic failure.

Husbands things
My husband bought this. I don’t know much about it but he has zero complaints. He bought it for a boat. He has fixed up 2 boats, sold one & we kept the other. So he apparently knows what to buy & how to use it.
