Product Details

The Manley 11332-8 Race Series intake valves are engineered for bracket racing, oval track competition, and high-performance street engines. Constructed from NK-842 stainless steel with a chrome-plated stem and hardened tip, these valves are built to withstand the demands of aggressive engine builds while maintaining long-term durability.

Each valve features an undercut stem for improved airflow, a swirl-polished finish, and fully machined construction to tight tolerances. The Pro Flo underhead profile (12° × 3/8 in.) promotes efficient charge movement into the combustion chamber, making these an excellent upgrade over OEM intake valves.

An easy to navigate website, great prices and efficient company. I will definitely check Autoplicity first for all of my automotive needs. From purchase to arrival I was well informed as to the status of my order.

Great, fast and easy. Wish there would have been an area to put a note as I wanted to ask for a tracking # when these are sent out...Thanks

I saved over a hundred$ on a set of electric cooling fans. so the prices r great but it took 4 days to process and ship my order so well see how long it takes to get here but overall I would rather save money than get fast shipping

Best price for the optima battery I needed for my boat, I will definitely add this site to my favorites.

They made a mistake with the shipping address, but, they took care of it very politely and professionally. Very nice. Thanks.

Very quick on shipping, at a great price.
