Nitrous Express Dual Stage Billet Crossbar (50-300 & 100-500HP) 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. Certificate of Origin Warranty

Do one oil change myself and it’s more than paid for.
Color: Silver, Color: Silver
It is 74 mm. It’s nicely made of cast aluminum. It has a rough cast finish so it shouldn’t be difficult to hold on to. It does fit my Lexus filter and the price is very reasonable. It also fits the oil filter on my 1999 (antique) Harley Davidson Heritage Classic. Which is the primary reason I ordered it. I don’t know this for certain but I suspect it will fit all HD EVO engines. That would be 1984 through 1998 except the Heritage which didn’t change to the 88 Twin Cam until 2000.
