BMW 135i – BMW Performance Spoiler Install

A big box showed up on my doorstep this weekend…

…and a BMW Performance replica spoiler was inside! The BMW 135i comes with a spoiler from the factory but its tiny and unflattering. This car is begging for something more aggressive. I had to install it right away.

I ordered it on Amazon for cheap. It was already painted to match and fit perfectly. Order yours here: https://amzn.to/2rA6byr

BMW 135i – BMW JB4 Install (N54)

I finally pulled the trigger on JB4 and decided to order the BMS clutch stop at the same time. Both products arrived in a few days and I installed them right away.

When I bought the car, the previous owner told me it had some sort of JB tune that was wired inline with the MAP sensor. After doing some research, I thought he was referring to JB+ which would increase boost an additional 2-5psi for an extra 20HP.

Before I could install JB4, I had to remove the JB+ chip that I thought was in the car. I removed the whole intake assembly but found no trace of the chip. I assumed the previous owner lied about it and continued on with the JB4 installation. Once I popped the ECU box open, I saw wires with electrical tape and some sort of aftermarket box with a toggle switch connected to it.

Since I was confused, I posted up a few pictures on N54tech and Terry identified it as a really old version of a pin-out JB3 tuner. The toggle switch was in the “off” position, so he advised me to carefully remove the harness and plug the wires back into the factory ECU connectors.

BMW 135i – BBS LM Replica Wheels Installed

My APEX TPMS sensors came in so I was able to get the new wheels mounted. I dropped the car off and couldn’t wait to pick it back up…

BMW 135i – Unboxing ESR Wheels

You know what that means, right?

…summer wheels! After the first week of April, it’s about time.

My first round of parts for the car are a staggered set of ESM BBS LM replicas with Hankook Ventus V12 tires and APEX TPMS sensors.

  • Front: 18×8 ET 35 – 215/40/18
  • Rear: 18×9 ET 40 – 245/35/18

I had to unbox/test fit them. I’m pretty impressed with the outcome.
