Ultimate E36 Catch Can Kit

This is the Rolex of catch can kits for the E36. No cost is spared; it is a truly professional setup that is right at home on any race or drift car. This it can be used on any M50, M52 or S52 engine that has the metal valve cover. If yours does not have the metal valve cover, they are interchangeable and are available from early models very cheaply on eBay. 
 
This kit comes with everything needed to install the catch can system from start to finish, including the drill bit, tap and professional quality AN hose, fittings and the super nice Imrpved Racing catch can. Nothing is rebranded (laser engraved) alibaba sourced BS here! 
 
The Standard Kit Includes:
Swivel Bulkhead -10 AN Fittings, nuts, and drill bit to install into the valve cover
Special rubber/stainless steel sealing washers for the bulkhead fittings
Valve cover side plug and tap to install into the valve cover
2x -10AN 90* elbows to attach to the catch can
10ft Black-10AN hose
Improved Racing .5L catch can, with filter venting to atmosphere
 
The Exhaust Venturi Model is similar, but includes:
10 more feet of hose
Two exhuast venturi 
2x 180* -10AN hose end fittings to go on the catch can to the venturi
2x straight -10AN hose end fittings
Improved Racing Vent Adapter 
This kit version uses exhaust flow to draw vacuum from the catch can/valve cover
 
This kit requires drilling into the top of your valve cover, as it vents from the original baffled area of the valve cover, and plugs original vent exit. Please note, the nuts cannot fall into the engine even if they vibrate off (they have never done this when installed with loctite) as they cover plate retains them. The OEM vent exit is notorious for getting in the way of aftermarket fuel rails and does not flow well. This kit fixes that issue and lets your engine breathe freely. Tap included to thread the vent exit for the supplied plug. 
 
All in all. The best you can buy.
