The ALTA Turbo Hot Side Boost Tube
In many cases MINI takes steps to help hide the true soul of a turbo. The boost tubing is no exception. MINI engineers attempted to remove some turbo and boost noise by placing, of all things, a muffler in the boost tubing. In the same fashion as an exhaust muffler is restrictive to performance, so is this! ALTA product designers created a simple, attractive way to remove this muffler and increase performance.
The ALTA Turbo Hot Side Boost Tube replaces the restrictive plastic and rubber OEM piece with a 5-ply silicone, fiber reinforced tube. With a mirror smooth interior surface, larger diameter and tapered transitions, you get a dramatic decrease in restriction and turbulence.
By removing the muffler you get a nice, deep, and mellow tone to the turbo and a leap forward in power. The silicone hose is restriction free with its smooth surfaces and larger internal volume. With the features listed above you get much better boost response and more horsepower! Check out the DYNO CHARTS to see the 10 WHP and10 Ft-Lbs Torque.
Available in Black, or Red.

Great price
I love Mann filters. Great for the price and great quality. I was surprised how cheap they were ( my car takes 2 filters and two come in the box). They fit like a glove and now I am enjoying fresh air

Can’t beat MANN quality
Bought to replace the filters on my 2015 bmw x5 as there was a musty smell from ac. Old filters were another junk company that fit very loosely. I was impressed by the quality and how secure the MANN filters locked into the housing; musty smell all gone now! Easy 10min replacement job, comes with VERY detailed instructions for the less mechanically inclined

Great product
Fits our 2012 X5d perfectly. Do yourself a favor and youtube the process for replacing these. You'll see it's well worth doing yourself rather than paying a shop that charges a BMW premium on everything.
Also something I learned recently... this is a low cost high charge item at the mechanic. A lot of times when they suggest replacing these it's because they just tick the box and don't actually look at them. We had our mechanic admit this on a recent service where it was suggested to replace, when we had just done it ourselves in April.
