Oil Drain Kit

The product is very well thought out and executed. The install can be a little tricky if you dont plan on removing a bunch of parts. Shrink within the freezer for a few hours before you tap it in and it will be good to go. Thanks again.Justin Kramer (20 May 2019, 18:07)

Excellent bit of kit

Got this sent over to the UK as there was nothing like this available. It fits perfectly and sits tight with no leaks. I followed the instructions and it was a breeze to fit as long as the throwback arm is removed. I've recently changed the hose fitting and it never moved from the block so seems to be a very secre fit. Very impressed.Mark Traill (16 Jun 2017, 15:04)

Turbo return fitting

Fits nice and tight, just follow the instructions and put it in your freezer before your going to hammer it in. Perfect if your not wanting to tap your block.David Beum (2 Jan 2016, 14:25)

It really does take some effort to hammer it in!

Follow the instructions to the tee and installation will be breeze. I installed this fitting on a 760, one tip is to remove oil filter re-locator arm to have enough room to hammer the fitting into the block. First time around there was not enough room to hammer. This fitting is ideally what you need if you have upgraded your turbo to a 15g/16t. I ordered the Teflon hose and fittings for the oil return/turbo side from Kingugawa(good prices and quick shipping). I would recommend this fitting to anyone who is tired of dealing with hard line pipe for the oil return.Hermilo Martinez (15 Aug 2015, 09:29)

Perfect fit and finish

This piece is a nifty and functional little upgrade to the o-ring'd hard pipe on B230FTs. I followed the Yoshifab instructions and installation only took about 30 seconds once I cleared space to work. It's a real shame I won't be able to put it to use considering I'll be parting the car before too long. Really handy piece, thanks team Yoshifab!David W (28 Jul 2015, 21:00)
