Looking to increase the efficiency of your stock oil cooling system in your 2007+ BMW 335i? Take a look at the MAPerformance BMW 335i Oil Cooler!

The BMW 335i comes with a factory oil cooler, but it’s small in size and is known to heat soak under heavy load. This is rather inconvenient for folks that run the car hard on the track, and dont want to risk the vehicle going into limp mode. By installing a MAPerformance BMW 335i oil cooler, you eliminate the risk of heat soak, even when increased boost pressure and engine stress. Take a look at the guide and use it for reference during your BMW 335i Oil Cooler installation!


BMW 335i Oil Cooler Installation Guide!

The installation is fairly straight forward. You’re going to be removing the front bumper, modifying the factory air dam and installing a distribution block on the factory oil cooler sending unit. From the distribution block, you run the new cooler lines to the cooler unit located behind the bumper. Let’s get started!

First, lift the vehicle. Drain the oil by removing the oil plug on the oil pan. Allow as much oil as possible to drain to reduce the mess created later by removing the factory cooler lines. One the oil has completely drained, replace the plug and begin removing the front bumper.

The first step in a BMW 335i Oil Cooler installation

The first step in removing the bumper is to remove the three 8mm screws attaching the fender liner to the bumper. With those removed, gently peel back the liner and remove the two 8mm screws that attach the bumper to the front fender. After that, remove the underpanneling attachment screws, they are 8mm. Then, remove the T30 Torx bolts on top of the bumper that attach to the core support. The last step in removing the 335i front bumper is to disconnect the headlight washer covers, and this can be tricky. We had the best luck using an interior trim tool and pick, but you can use whatever is easiest and wont damage your paint. Gently pry out the cover and press down on the springs with the pick. The cover should come off, and you can gently pry off the retainer clip after that.

With the bumper off the car, you can begin removing the air induction pieces. The air intake air dam is held on by two T25 bolts and a few body clips. The air dam shroud is surrounded by a core support brace that needs to come off by removing the three T30 bolts. Remove this, and set the shroud aside. You’ll need to cut this to allow room for the BMW 335i oil cooler. See the image for reference on where to cut.

Attach the banjo fitting to the oil cooler’s lower fitting. Make sure to use tephlon tape or liquid tephlon on all fitting threads. Now you may install the oil cooler on the car. Start by attaching the top and lower brackets to the oil cooler. You’ll be using the two forward-most outer holes on top of the core support to mount the cooler. With the MAP BMW 335i oil cooler centered, it should line up perfectly. You may then attach the lower brackets to the lower core support using the supplied hardware.

With the BMW 335i oil cooler mounted to the car, its time to start running the lines. To do this, we need to remove the factory fan. Start by unplugging the wiring harness, then remove the one T25 bolt. Gently lift the pan up and out of it’s mounting holes and set it aside. Remove the factory oil cooler lines from the sender by removing the T30 bolt. Let the lines drain as much oil as possible. Take the supplied oil distribution block, insert the supplied O-Rings, and install on sender unit with factory oil lines on the bottom in the same orientation as they were removed. Tighten the securing bolt.

Next, move on to your new oil cooler lines. Begin by modifying your air dam to allow your new lines to pass through. The easiest way to do this is to take a utility knife and cut an X into the dam. Take a look at the image for reference on where to cut. Make the holes large enough for the fittings to pass through, and install it on the car. The oil return line is the drivers side fitting on the cooler, and requires 44″ of hose. The feed line is 60″ and attaches to the the lower fitting (where we attached the banjo fitting). Cut and assemble the hoses based on the dimensions above and install on the car, tightening all fittings at the BMW 335i oil cooler and the distribution block.

With all the fittings tightened and the lines connected, replace your oil filter and fill oil to capacity. Start the car and allow it to warm up while checking for leaks. This will allow the oil to populate the new cooler and all lines. Shut the car down and fill to capacity again. You should expect to add an additional 1-1.5 qts of oil with the additional cooler. If all checks out and no leaks are present, you may reinstall your bumber and enjoy the benefits of cooler oil!
