FAST Intake Manifold LSXHR LS1/2/6 (Cathedral Port) - 146303

$1,163.86
The FAST LSXHR 103mm Intake Manifold is ideal for generating maximum power in boosted and naturally aspirated GM LS cathedral port engines. It ships with a set of “tall” removeable velocity stacks, however “medium” and “short” stack options can be purchased separately. This allows interchanging of the various runner lengths so racers can experiment with finding which combination makes the most power in their application. Its polymer construction is lightweight, very strong and virtually eliminates power-robbing heat soak that occurs with commonly available aluminum intake manifolds. The manifold has been optimized to make power from 5,000 to 7,500 RPM, with testing showing 20+ horsepower gains over competitor tunnel ram intake manifolds. The FAST LSXHR 103mm Intake Manifold is designed specifically with boosted applications in mind and is rated for up to 45psi of continuous boost pressure. The compound fuel injector angle aims the spray pattern for ideal atomization, resulting in maximum power production and superior drivability. Also included with the intake manifold are custom fuel rails and necessary hardware. 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. Additionally, its 103mm throttle body opening can be port matched up to 105mm.

RCA Is Here to Deliver

We have been in business for more than 2 decades. Our goal is to simply have the largest selection of in-stock parts and the fastest shipping possible. This has helped us fine tune our formula for fast shipments, the best customer service and the industry’s best deals.

Our shop, RCA Garage, installs the parts we sell on a daily basis. If you are local, feel free to contact us for installation or simply come visit our showroom.

Aside from selling and installing parts, we buy the same parts for our cars to use in daily life and motorsports. This is why we feel we have the edge when it comes to parts knowledge.

Here are the most common questions that we get from customers. If you do not see your question or need more information, please contact us.

  • Are there any coupons I can use?
    Our pricing is so good, we rarely need to offer coupons! But we still run deals from time to time. Check our blog for any special deals or sign up for the news letter for the latest news and discounts.
  • How fast will I receive my order?
    Orders are shipped either same or next business day. Delivery times vary by location, but on average take 1-4 business days. You can always check with us first to confirm delivery time or go to checkout to see an estimated delivery date.
  • Will this fit my car?
    Plug in your car to confirm fitment. Our car filter is very accurate, but is not bullet proof. If you have any doubts, feel free to contact our experts to confirm all information.
