SpeedFactory Catch Can Hose & Fitting Kit
If you're plumbing a catch can on a turbo B series, the can is the easy part. The lines are where builds stall: sourcing the right mix of -10AN fittings, finding M28 adapters for the block ports, and figuring out valve cover bungs. SpeedFactory packaged all of it into one catch can hose and fitting kit so you're not piecing together an order from three different fitting catalogs.
What It Is and Why It Works
Every kit starts with the same plumbing foundation: 10 feet of SpeedFactory -10AN black braided hose and eight black anodized -10AN hose ends, split into four 90 degree, two 45 degree, and two straight fittings. That mix covers the bends you actually hit routing lines from the back of a B series head to a can mounted on the shock tower or in the old battery tray, and -10AN is the line size proven on high-boost Honda builds. Guys logging crankcase pressure on 700 plus horsepower B series setups run exactly this size for a reason: smaller lines choke crankcase flow under boost.
The B series kits add the engine-specific hardware. Two billet M28 to -10AN adapters thread into the factory ports on the back of the block, flanking the oil filter, where the 14mm allen plugs live from the factory. Two -10AN male weld fittings go on your valve cover for the top-side vents. The SF-02-601 kit finishes with a billet B series breather port plug to block off the OEM breather. The SF-02-602 kit swaps that plug for a crankcase pressure port fitting instead, which gives you a dedicated spot to run a pressure sensor. If you're making serious power and want your ECU or logger watching ring seal in real time, that port is worth the small step up.
The universal kit (SF-02-600) is just the hose and the eight hose ends, no engine hardware. That's the pick if you're plumbing a K series, an H22, or any setup where you already have your block and valve cover fittings sorted.

Fitment
| Kit | Application |
| SF-02-600 | Universal, any -10AN catch can plumbing job |
| SF-02-601 / SF-02-602 | Honda and Acura B series engines (B16, B18, B20) |
The B series kits fit any chassis running a B series: EG and EK Civics, DC2 and DB8 Integras, CRXs with swaps, or anything else with a B16, B18, or B20 between the strut towers. The block adapters use the factory M28 ports, so no drilling or tapping on the block side.
What to Know Before You Buy
The valve cover fittings are weld-on. B series valve covers are aluminum, so plan on TIG welding, and if you can't do it yourself, budget for a fabricator and a day or two without the cover. If welding is off the table entirely, the universal kit plus a pre-bunged aftermarket valve cover gets you to the same place. Also worth knowing: the M28 block ports sit behind the intake manifold on most B series setups, so they're far easier to install with the manifold off or the engine out. If you're mid-build, do it now instead of after everything is bolted together.
This kit does not include the catch can itself. Pair it with one of the SpeedFactory catch cans, and if you're boosted, go with a multi-filter can rather than a small single-filter unit, because a high-boost B series moves more blow-by than a can the size of a soda can will handle. Pick the SF-02-602 version if there's any chance you'll want crankcase pressure logging later. Adding the port after the fact means pulling fittings back out, and the price difference between the two B series kits is small.
