BMW 135i – BMS Dual Cone Intake Install (N54)

Last week, I scored a used BMS Dual Cone Intake kit on 1Addicts for only $25 shipped! It was just too good of a price to pass up. When I opened the box, I found a pair of very dirty white filters. I regret not taking pictures of them because they almost looked black.

After soaking them with degreaser and rising them off, they looked brand new again! A couple minutes in the sun and they were dry. Then I grabbed a can of K&N filter oil and sprayed a nice coat on top. To my surprise, the oil was red! My precious white filters were no longer white! Oh well… they still look great.

BMS claims that these puppies add at least 15HP to the wheels. I’m not sure how accurate that is but the sound is intoxicating! I had no problems with the K&N panel filter in the OEM airbox, but I read that it can be restrictive at higher boost levels. For only $25, I couldn’t go wrong with these. A quick test run proved that the car pulls great and sounds much better. Plus, I like the look of these under the hood.

BMW 135i – BMS Oil Catch Can Install (N54)

When I bought the car, it came with a Riss Racing oil catch can. Good news, right? Well, not so much. After realizing how small the lines were, I couldn’t stop thinking about it. Why wouldn’t they utilize the large lines that the stock PCV system had? Plus, it’s mounted on the hot side, right on top of the turbos! Definitely a re-branded eBay part.

Anyways, I bought a BMS OCC because it’s built from the ground up specifically for this car. It’s hoses exceed the OEM PCV piping in diameter and that flow rate is maintained throughout the entire catch can ensuring no excessive crankcase pressure buildup. Unlike the Riss Racing can, the BMS version is mounted on the cold side underneath the cowl for a stealthy look. Holding the two, the BMS oil catch can is the winner, hands down. Gotta love Terry’s products.

Much better. The hoses are nice and thick and you can’t even see it once the cowl is back on. Very happy with the upgrade.

BMW 135i – Fuel-It Stage 1 Fuel Pump Install (N54)

I ordered Steve’s Walbro 255 inline fuel pump kit so I could run up to 100% E85 for more power. The factory LPFP could handle a smaller mix of E85, but it was maxed out at that. I met up with Bob for help with the install. He has installed the pump before and also has the flashing tools and software. We installed the pump this weekend and flashed the ECU with a free E85-specific flash that BMS offers.

First step: remove the fuel pump bucket from under the rear seats…

As you can see in the picture above, we unplugged the connections first. I didn’t take any pictures of the actual removal process. It’s fairly straightforward if you follow Steve’s instructions. Here it is, removed:
