FAST has developed the industry’s first polymer tunnel ram-style intake manifold, ideal for generating maximum power in boosted and naturally aspirated engines. Available for rectangular port LS3 and raised rectangular port LS7 engines, the FAST LSXHR FAST-RAM Intake Manifold features removable stacks of various lengths, so racers can experiment with finding which combination makes the most power in their application. Its polymer construction is not only lightweight and high strength, but also virtually eliminates power-robbing heat soak that occurs with commonly available aluminum intake manifolds. Testing has shown an average 30-horsepower gain between 5,000 and 7,500 RPM over competitor tunnel ram intake manifolds. The FAST LSXHR FAST-RAM Intake Manifold is designed specifically with boosted applications in mind and is rated for up to 45psi of continuous pressure. Compound fuel injector angle aims the spray pattern for ideal atomization, resulting in maximum power production and superior drivability. A reversible top allows for forward- or firewall-facing throttle body installations. The intake manifold also features two nitrous nozzle bosses per runner for clean and easy direct port system installations. Its 103mm throttle body opening can be port matched to 105mm.

Good to know

Questions, answered straight.

If it is not here, call or text the counter. Real people, real answers.

Fitment

  • Will this fit my truck?

    The Fits section at the top of the page lists the manufacturer's applications for this exact part. If your year, make and model is not there, or you are not sure, text us a photo of what you are replacing with your year and engine and we will confirm it before you order.

  • What if I order the wrong part?

    Call or text us before it ships and we will swap it. After delivery you have 30 days to return it in new, uninstalled condition. The return policy has the restocking details.

Shipping

  • When will it ship?

    In-stock parts usually ship within 1 to 2 business days from warehouses across the USA. The stock line under the options tells you the status of the part you are looking at. Large items ship LTL freight and we call to schedule delivery.

  • Why did I only get part of my order?

    We ship from multiple warehouses, so an order with several items can arrive in more than one box. Tracking for each shipment is emailed as it goes out. Full details in the shipping policy.

Returns and warranty

  • What is the return policy?

    30 days from delivery, in new and uninstalled condition, with a restocking fee. Everything is spelled out in the Returns & Refund Policy.

  • How do warranty claims work?

    We are an authorized dealer, so the manufacturer's warranty applies to every part we sell. Call or text us with your order number and we handle the claim with the brand for you.

Paying

  • Can I pay over time?

    Yes. Shop Pay installments are offered at checkout on qualifying orders, and the monthly estimate shows right under the price.

  • What is a core deposit?

    Some remanufactured parts, like injectors and turbos, carry a refundable core deposit. It is shown on the product page when it applies and refunded when your old part comes back to us.
