Oversized Stainless Steel Performance Valves (single or full sets), 03-05 Neon SRT-4

THESE ARE BACK IN STOCK! After being out for almost all of 2020/2021, we have them back in stock again!! Now you have the option to buy them individually or as a set.

Want to improve the flow of your Neon SRT4/PT cylinder head? Planning on doing some head work and want to make sure your stock sized valves don't hold you back?

If so, then you need to get a set of these oversize performance valves for your Neon SRT-4.

The cylinder head used in the Neon SRT-4 is the same as what was used in the PT Cruiser/Caravan, etc. This cylinder head was more optimized for fast warm up of the catalytic converter to reduce emissions, as well as for fuel economy. The valves used in the SRT4 cylinder head are well known to be smaller than optimal, especially with the stock exhaust valves!

So, we've come up with this kit : 1mm oversize intake valves, and 2mm oversize exhaust valves. This improves the flow of air into the combustion chamber and improves flow out greatly.

These valves are made of high purity stainless steel and they are hardened to withstand lots of abuse and heat. The back sides of the valves are swirl polished to improve flow of air into the cylinder.

Please note: These valves are single groove keeper type, whereas the SRT4 uses a triple groove keeper. The keeper, in case your not familiar with what it is, is the lock that goes on the top of the valve to keep the valve spring and retainer in place. In order to use these valves, you'll need to use single groove keepers (we sell them separately).

Note2: These valves are very difficult to get ahold of now, and we may periodically change suppliers to try and keep these in stock. These valves are shown in black, but may also be silver (polished stainless).
