One of the most important components of any nitrous system is a good filter. NOS filters feature an aircraft-type reusable stainless steel mesh filter element to keep contaminants from attacking a solenoid and plugging the jets. These new NOS hi-flow billet aluminum filters feature a precision 2024 billet aluminum body and a 140-micron serviceable stainless steel mesh filter element that has 10 times the filtering area of a standard filter. Our filters feature a radius on the outlet fitting to maximize flow and are available in a variety of sizes depending on your needs.
The NOS 4AN Hi-Flo Nitrous Filter seems to be doing its job just fine. However, the installation instructions could've been clearer. It took me a bit longer than expected to get it all set up. Once it was in place, though, I did notice a smoother nitrous flow. Just be prepared for a bit of a learning curve!

Great upgrade for my nitrous setup
I recently installed the NOS 4AN Hi-Flo Nitrous Filter on my car, and it's made such a difference! The black finish looks sleek, and it fits perfectly with my existing setup. I've noticed an improvement in the overall performance since I swapped out the old filter. Highly recommend it for anyone serious about their nitrous system!

Arrived damaged, but still functional
I was excited to receive my NOS 4AN Hi-Flo Nitrous Filter, but it came with a dent in the casing. Thankfully, it still works fine, and I'm using it in my nitrous system. Just a bit disappointed in the shipping quality. Hoping the next one comes in better shape!
