Easy Question . .

Do i have to buy a certain type of boost gauge, or can I buy a universal boost gauge for the 135i. I saw ECS and Prosport were options; any other boost gauges that you guys like? Thx.

I have an e90 friend who runs the Prosport. No complaints there. His was about $100 new. Here is a sample photo of one mounted in a 135i http://www.e90post.com/forums/showthread.php?t=460335. themyst may still have it for sale if you want to save some money.

I personally think you should spring the extra dough and get the P3Cars Vent Gauge. Read up on it and have a look at the photos and videos here -

I just installed this thing yesterday and it is amazing. It provides all the functionality listed above, in a single gauge (not multiple pods) with an OEM look and feel.

These options represent both sides of the spectrum. It just depends what you are in the market for and how much you are looking to spend.

That's the gauge I am going for. Sleek, sexy, OEM styling and it doesn't look cheesy..


I'll chime in on the Prosport, as I had a Prosport premium on my WRX.

You'll have to do the extra wiring work, which I wouldn't do on these cars, but had no problem on my WRX.

There are no directions for your specific car and you'll just have to figure it out. I ended up just tapping the fuses. They come with no taps, and I had to buy my own. The wires are about 10'' long off the plug-in for the gauge which means you have to buy extra wiring to extend each line. You'll have to run your lines through the firewall and the sender line through the firewall. You'll need a mounting solution. I purchased the premium so it came with a gauge cup and hood with 3M tape. I wouldn't do that to a BMW. They constantly need to be re-calibrated as the gauge will often read too high or too low.


I'd save up, or spend the extra cheebah on the vent gauge. It's simple, comes with instructions, and is more than just a gauge and can even hook up to WB02 with LC-1.. Pretty bad ass...
