Extreme Turbo Systems Anodized Gold 5.0" Intercooler Upgrade w/ Stencil BMW 135i | 335i N54 Twin Turbo 2005-2016
$939.00

If you're looking to boost your BMW's performance without getting into the nitty-gritty of heavy modifications, let me tell you about the Extreme Turbo Systems intercooler upgrade. This isn't just another shiny piece of gear; it's a game-changer that I’ve had the pleasure of installing on my own ride. You know how the stock piping can really hold back your engine? Well, this setup replaces that restrictive stock piping with some serious stainless steel goodness. And trust me, it’s a direct bolt-on—no cutting or crazy modifications required.

Now, let’s talk numbers. This intercooler can give you max horsepower gains of up to 21.05 hp. That’s not just a marketing gimmick; you can actually feel the difference when you hit the gas. Plus, it keeps your engine running cooler—over 60 degrees lower temps, to be exact. That means no heat soak after a pull, which is a huge win when you're pushing your car hard. And if you're worried about engine knock, this setup helps reduce that too, so you can drive with confidence.

The build quality? It's solid. We’re talking durable stainless steel piping and 4-ply silicone couplers that can handle the heat and pressure without breaking a sweat. Oh, and those Breeze premium T-bolt clamps? They grip like a vice, ensuring everything stays put even under heavy use. This intercooler works on both the N54 (twin turbo) and N55 (single turbo) engines, which is a nice touch for folks with different setups. Just a heads up, if you're going with the 7-inch version, you’ll need to do a little trimming on your bumper cover, but it’s nothing too crazy.

For fitment, this upgrade is perfect for the BMW 135i (2008-2013) and 335i (2005-2016). If you’re serious about squeezing out every bit of performance from your BMW, this intercooler is definitely worth considering. I’ve seen the ETS test results on their 5-inch front mount intercooler, and it really speaks to the quality and effectiveness of their products. So, if you’re ready to take your driving experience to the next level, this is one upgrade you won’t regret.
