    Need some help with air intakes for my 13 RXPX

    Sorry, I searched and read product descriptions and I'm still confused -- sorry for the questions which I'm sure have been answered in the past...

    I have a 13 RXPX with the Vtech 8350 and a 14/19 -- RPMs are a little lower than I expected (7900-8000 depending on temp) and top speed is indicating 73 on the speedo.

    I want to do a few more mods to get the revs up in the 8200/8300 range. I want to add an intake manifold upgrade kit (easy) and a 4" intake (which is where I'm getting confused.)

    Most threads say to go with the Kanaflex DIY kit because it's cheaper and as effective as the name brand kits. The online store says it needs a catch can (which seems to be an additional $140?) Now it's pretty much the same price as the R&D 4" kit (which doesn't say it requires a catch can?)

    Speaking of R&D, then there's a "Cool Air Power Plenum" kit. Is this something different than the 4" kits mentioned above?

    Really appreciate the help

    I have a diy 4" on my PX and a R&D on my TX. I really like the R&D kit. It makes for a clean install. The Power Plenum kit is really only a filter and I prefer the full 4" kit. You do not have to run a CC with the R&D, but I do run one.

    you will still want to run a catch can with the R&D kit, or any air intake kit for that matter.
    The catch can prevents crankase oily vapors from being recirculated into your engine. These oil vapors will coat your intercooler making it less efficient reducing performance. Also, crankcase vapors being rebreathed by the engine will reduce the knock rating of your fuel. Running a catch can on a supercharged ski is one of the best things you can do!
