Nitrous Express 4150 RNC Conventional Nitrous Plate Kit w/.375in Solenoid w/15lb Bottle (55140-15)The conventional RNC (Restricted Nitrous Class) systems are the first choice for professional racers that are limited by jet size. These systems feature a CNC billet nitrous plate with enlarged nitrous passages, a . 375" orifice Lightning nitrous solenoid, 8an feed line and a . 500 orifice Lightning 500 bottle valve. The combination of these components results in a very dense liquid nitrous charge which allows the maximum amount of nitrous flow

The conventional RNC (Restricted Nitrous Class) systems are the first choice for professional racers that are limited by jet size. These systems feature a CNC billet nitrous plate with enlarged nitrous passages, a .375" orifice Lightning nitrous solenoid, 8an feed line and a .500 orifice Lightning 500 bottle valve. The combination of these components results in a very dense liquid nitrous charge which allows the maximum amount of nitrous flow through a certain size jet. Results of these RNC systems are so impressive that you will have to use one to believe it. Nitrous Express RNC (restricted class nitrous) systems are guaranteed to make the most power per jet size of any system on the market. If you don't make the most horsepower or are not 100% satisfied, NX will gladly refund you 100%.

    Just okay
    Color: Grey Striped, Size: 72"W x 84"L (Pack of 1)
    Okay curtain, not great, but not bad. Looks like it has kind of a faint background design. Has a plastic type feel. Looks okay.

    Pleasantly Surprised!
    Color: Grey Striped, Size: 72"W x 72"L (Pack of 1)
    I was looking for this exact product but didn’t know it! We recently moved into a new home and had zero window treatments so needless to say I wanted something quick, affordable and not vinyl WalMart blinds. We are happy with our purchase and would highly recommend to others. Some complain of the adhesive not sticking- make sure to clean the window wells/walls etc prior to installing these. If the surface is free of dirt/grease there will be no issues with them staying put.
