BMW 135i – LUX H8 Angel Eye Upgrade

After owning my 1-series for over a year, I finally got sick of the halogen angel eye bulbs. I previously coded their voltage intensity up higher to make them brighter, but I still didn’t like the warm color.

So, I decided to buy myself an early Christmas present! LUX was running a sale, so I grabbed a pair of their latest and greatest angel eyes. Their H8 angel eyes advertised a pure white 7000k temperature with extreme brightness. Perfect!

I received them a few days after ordering and wanted to install them right away. All I had to do was pop the rear headlight covers off. They can be finicky, but you’ll figure it out. After the cover was off, I twisted the old bulbs out. Next, I inserted the new bulb and tucked the power supply box out of the way. Drum roll please…

BMW 135i – Rieger Rear Diffuser Install

I finally got around to installing these two cosmetic parts that have been sitting in my garage. I bought the Rieger diffuser used and the carbon fiber hydrodip was fading. Time to get to work!

BMW 135i – Serpentine Belt Issues and Fix (N54)

A few weeks ago the car started making a squeaking noise. So, I popped the hood and started taking a video. Here is what I found:

As soon as I noticed the shredding serpentine belt, I drove home and parked the car. Ordered a new belt and tensioner, along with oil filter housing gaskets (#1 & #2) because mine were leaking. Once the parts arrived, Bob helped me install everything. Here is a picture of the OFH gaskets going in, what a mess…

Obligatory picture of the shredded belt:

BMW 135i – Interior LED Conversion

Why do cars still come with halogen headlights and crappy interior bulbs? It’s 2015, Xenons and LEDs should be standard issue, since the 1 series is pretty old – I decided to take it upon myself to upgrade the interior lights.

I finally ordered some LEDs from ECSTuning. They sell a full LED kit for the 135i, but it’s marked up an additional $15 for no reason. So, I bought everything individually to save some cash. (1) overhead kit, (1) glovebox bulb, and (1) trunk bulb for a total of $41.33 instead of $54.95… you’re welcome. Here are my results:

BMW 135i – OMGSplitters Front Splitter Install

It was just another day browsing 1Addicts when I stumbled upon a thread about custom front splitters by fmxomar. There was a ton of interest, but no one had installed one yet. For the price, I figured I’d pull the trigger on the front splitter and a set of side splitters.

I thought these two items would flow perfectly with the Rieger rear diffuser that I’ve had my eyes on. The parts arrived within a week and came with installation hardware, but no mounting holes. I guess that’s what a drill is for! First step: remove the front bumper.

BMW 135i - front bumper removedI started off by clamping the splitter to the bottom of the bumper and then lined everything up. 9 holes later and it was attached. I still wanted to mount the OEM wheel wind deflectors, so I trimmed 1/2″ notches in the back of the splitter to make room.

Because both parts are plastic and the splitter wasn’t structurally mounted, I didn’t want to take the chance of it folding under at high speeds. So, I installed two APR support rods. It took a little courage to drill into a perfectly good front bumper, but it was a risk I was willing to take. I followed the center-flow design and made sure to use large washers on the back of the bumper. Everything was secure so I quickly re-mounted the front bumper. It is a very sturdy setup.
