I was also initially worried about the location of the lines over the turbo, but the STI PCV lines are literally laying on top of the turbo heat shield with no issues. Also seems easy to remove if you wanted to empty by removing the entire top instead of using the large drain plug on the bottom. Has a dip stick and AN fittings at the can. Piggy backs the stock PCV system, acting as a second line of defense, catching what the stock PCV missed. Also doesn't look like you can use the engine cover without modification (boooo). Seems like without a baffle under there you'd be sucking up more oil than oil vapor. Only catch is I question the design of the CNC'd plate.
If it had a dip stick, it would be at the top of my list. I think this is a better plate design than the CTS (has a baffle in place), with one big exception NO DAMN DIP STICK! Seriously, not only am I paying a premium for quality materials, but you're going to make me remove the entire can from the car to check the level? I guess you could just hook up some sort of hose to the t-valve on the bottom and try to drain that way. So with that said, let's look at the options again. Wouldn't it make more sense to piggy back the stock unit as a second line of defense? Has BFI figured out a way to make a more efficient catch can AND somehow sell it for less? It has AN fittings on the can, stock-like connections on the other end. Unless the CNC'd plates offered by IE and CTS incorporate some sort of pre-PCV baffling, it would appear that you're now relying solely on the catch can to do the oil vapor separation. My second (third?) issue was the fact that no one really knows if completely replacing the stock PCV system (IE and CTS) is any more effective than piggy backing the stock unit like the BFI. Since this isn't currently an option for the GTI, ease of draining/removal is a plus, as well as the ability to view the level inside the can via a sight tube/window or dip stick. I'm not worried about the other 'stuff' that's caught, that's what oil filters are for. Ideally, I'd like a true recirculating catch can that dumps the caught oil back into the oil pan like they do on the STI (IAG). What I really got hung up on was that none of my options were in my mind 'perfect'. Price came into account, even though I'm more than willing to spend more money for a superior product. But of course as I continued to research and ask for opinions from friends, and started to doubt myself. The BFI also caught my eye because of the different design. I initially narrowed it down to the IE and CTS options, mainly, I must say, for the quality of materials used and AN fittings. I've been doing the exact same research since I placed my order last week. What else is out there? What would you spend your $$$ on? CTS is the STRONGEST contender IF I can put the engine cover back on. Wildcard: 42 Draft Designs -if- there's a kit?
Pros: Good hose routing, quality components, has a dipstick.Ĭons: Can you re-use the engine cover? removal for draining appears to be a PITA.Ĭons: Bad experience with quality from this vendor (who offered to make it right, but by then too late), really piss poor hose routing, specious bafflingĤ2 Draft Designs: Don't see a Mk7 option as a kit.Ĭurrent ranking (if the engine cover is usable post install):
Pros: Integrates nicely, appears easy to drain.Ĭons: No dipstick, cheap connections, requires the APR intake to work (!?!?!?!), placement in bay is suspect. Pros: Appears you can reuse your engine cover, appears to not delete the PCV valve.Ĭons: Draining? Dipstick? Specious valving? OMFG price. Seems intelligent as I drive the ever living hell out of my GTI - I see the following available options: I'm seriously considering a catch can for my GTI. Mk7 GTI Catch Can Options - edit: Bought one! Brutally honest review unfolding.
