Product Details

The FAST 146302B LSXR intake manifold is engineered for cathedral port LS1, LS2, and LS6 engines, featuring a 102mm throttle bore for maximum airflow potential. Constructed from advanced polymer composite material, this intake manifold offers significant advantages over traditional aluminum designs.

Key Features:

  • 102mm throttle body bore maximizes airflow for high-performance applications
  • Cathedral port design for LS1, LS2, and LS6 engine compatibility
  • Advanced polymer construction reduces weight compared to aluminum manifolds
  • Superior heat dissipation properties keep intake charge temperatures lower
  • Increased structural strength and durability over aluminum alternatives
  • Attractive black finish complements modern engine bays
  • Direct bolt-on installation with factory mounting points

The LSXR series represents the evolution of FAST's proven LSX intake manifold design, combining race-proven performance with the benefits of modern composite materials. The 102mm bore supports high-horsepower builds while the polymer construction helps maintain consistent performance by resisting heat soak that can plague aluminum manifolds.

As the merchant name suggests, the process of my purchase was straight forward and simple. I do not need anything else , so next time I will shop here again.<br>Thanks.<br>Julio Gonzalez

These guys had a part that I was searching for for a long time. Not only that, but they had 2 in stock when nobody else did. I will definitely be looking here first next time I am buying auto parts.

good so far. received item on time, maybe even a little faster than I expected. the item was exactly as described, quality is good and exactly what I needed. it has been installed and works great. will do business with Autoplicity again. would definitely

Just received my wheel lock. It is exactly as described and came very quickly. Autoplicity has the cheapest price and great service.

I looked around for the best peice for a set of Sparco seats. I found them on autoplicity much cheaper then anywhere else. I figured it would take a few days to ship, but by the time i decided to call for a tracking #, I got an email with tracking # and that my seat was all ready to be delivered the next day. They didnt ship together because they were out of stock for a day or 2. I called about my other seat a few days later and it was already delivered at my door. Any future purchases will be checked with autoplicity 1st.

Easy

thnk you

Good service, fast shipping, excellent prices

Great deals and excellent prices, fast shipping.

This was my first time placing an order with Autoplicity and I would not hesitate to order from them again. The product was as described and shipping was very fast, received the item in 2 days. Good price too! Thanks Autoplicity.
