Nitrous Express GM EFI Dual Stage Jet PackNX Jets are manufactured on CNC equipment, and are guaranteed to be within . 0005 of specified jet size. In recent testing, using the same jet size, NX jets out flowed the competition by 35%! That's right 35% more flow through the same orifice, how you ask? The NX jet was designed to be more than just a hole in a piece of brass; its contoured inlet and multi stepped outlet allow turbulence free flow with no restrictions. Warranty Certificate of Origin

Top quality filters at a good price.
Style: 20x30x1
These filters are good quality. They are reinforced and hold their shape. They fit perfectly in my filter holder. The thing I like is that the filters were bundled together and shipped in a sturdy box. Other filters I have ordered showed up in a flimsy box and were damaged.

Great Fit and Noticeable Air Quality Improvement
Style: 12x24x1
I purchased the Filterbuy 12x24x1 MERV 8 air filters and have been very happy with them so far. They fit perfectly in my HVAC system without any gaps or issues during installation. After replacing my old filters, I noticed the air in my home feels cleaner and there seems to be less dust settling around the house. They do a good job of capturing everyday particles and allergens while still allowing good airflow. Overall, this is a reliable and cost-effective 4-pack of filters. Solid quality, easy to install, and a noticeable improvement in air freshness. I’ll definitely be ordering again.
