Race Series Valves
Intake
Individual Piece

Manley Performance Sport Compact stainless steel valves utilize our exceptional Race Series alloy and are manufactured to the highest quality standards.

Manley valves are designed to outflow and outperform all others even in the most severe environments. Manley stainless valves feature gorgeous yet durable chrome stems, swirl polished under heads, fully hardened tips, completely machined combustion faces, closely controlled margin heights, and exact stem to seat concentricity to render a finished product that is unsurpassed.

Manley intake valves typically are built with our original Pro-Flo design which reduces the stem diameter in the fillet area for increased airflow but also less valve weight.

In certain specific applications, Manley offers our Extreme Duty exhaust material. Our Extremealloy alloy offers more hot hardness and high temperature strength than our competitors offerings. This alloy is ideal for extremely high boosted applications where the exhaust gas temperatures reach what seem like unthinkable levels.

Manley stainless valves are suitable for all applications ranging from the mild street performer to the jaw dropping 1000+ horsepower race cars competing at the drag strip or drifting events.

Great communication and fast shipping using FedEx Home. My packages can even be delivered on Saturday. Great prices on hard to find parts. I would definitely buy from again. Thanks

I just received my Knn filter. Shipment was on time. The box look beat up and deformed with a lot of tapes but the filter seems to be in good condition.

Ordered some parts the other day and was impressed, will see if it was a fluke.

BEST PRICE AVAILABLE! QUICK SHIPPING.

Great Prices! and Great Customer Service thanks again!

Great price, free shipping and offered Amazon payments!!

Fantastic company! Great selection for every vehicle and fast shipping! I will definitely shop here again.

Fast ship, great price. I will purchase merchandise from them again.

Excellent service. I called in Monday for a hard to find item which I had ordered from several other online shops who despite saying were In Stock online were not actually in stock at all and the orders were canceled after waiting a week to find out. They had the item in stock as listed on their website and shipped the next day. The price was the cheapest of anyone who actually had the item in stock by a substantial amount.

Best price anywhere for a brand name item. Fast inexpensive shipping!

i was advised by all internet sources, and the manufacturer that the part i needed was out-of-stock and discontinued, when i used google shopping, autoplicity not only had the part but they were the most reasonably priced! my order was delivered to my door in 3 days. color me a satisfied customer, and yes i will used autoplicity again, soon!
