Nitrous Express 66042-10

4150 Dual Stage Billet Crossbar, (50-300 & 100-500hp) With 10lb Bottle.

The new NX Billet Crossbar nitrous plate systems have just raised the bar in nitrous plate technology. The CNC machined design eliminates round spray bars resulting in excellent atomization and cylinder distribution. With no spray bars to sag, rotate or disrupt airflow, this is truly the Next Generation in cross bar nitrous plate technology., , This system includes a 10lb nitrous bottle with the billet aluminum Lightning 45 bottle valve. This valve not only looks great; It is packed with features including two integrated gauge ports, 5/8 siphon tube, a large .325 orifice and an improved flow path with only one 45 degree turn. The Lightning 45 bottle valve looks great, flows great and weighs nearly one full pound less than our old style brass valve., , This crossbar nitrous system includes more than the standard crossbar nitrous kit. It includes a custom solenoid bracket, billet aluminum y fittings, braided stainless solenoid to plate lines, nickel plated fittings, wide open throttle switch, master arming switch, 40 Amp relay and relay harness., , This system is designed for 4150 flange manifolds and includes jetting for 50, 100, 150, 200, 250 & 300HP.,

Great prices. Fast shipping. Huge inventory.

Great so far.

Fast and easy

Great price. I will leave more feedback after it arrives and is installed.

Thanks , It was quick and easy .

Incredibly low prices and fast shipping. I bought shocks and struts for my truck and saved more than 35% over what my local parts store wanted!!! I made the mistake of not setting up my account before placing my order so I didn't get confirmation right away, but one quick phone call fixed that. Great customer service.

Very friendly customer service! They also shipped my radiator out very quickly. I will definetly be ordering from autoplicity again!

Easy to order and a great price - look forward to receiving my parts!

Quick and easy!

Quick and easy so far hopefully parts are what I need

I was searching for spark plugs and came across their web site and was surprised to see they had the cheapest price on the plugs I needed.

They have hard-to-find items that ship immediately, excellent turn-around time on the orders. I look here first.
