The stock plastic intake elbow on your BMW is a good
functional piece, but leaves power on the table. The sharp corner
creates flow turbulence and the shape of the part is less than
Designed using the same features as the intake
sections on our World Challenge racecars, this high quality
silicone replacement hose adds real power and throttle response.
With a reshaped profile, more filtered air volume is available,
essentially increasing plenum volume. This boot is the perfect
add-on for a performance panel filter or performance intake systems
that do not replace the factory plastic boot. High quality 4-layer
silicone construction will withstand anything you can throw at it
for years to come.
Fits all E46 M3 cars 2001-2006. Boot is intended to
fit both stock plenum/airbox and many aftermarket applications, and
therefore the ends will likely require trimming to fit properly and
provide smooth airflow for your specific application. We
suggest a new snap-blade knife and straightedge for this task,
measure and mark twice and cut once.
Great product but hard to fi

Great product to get more response from the throttle. But took a while to put on as the silicone boot is a bit of a tight fit. Make sure to trim it to the right length. Also buy some new bigger sized metal clamps to make installation easier. Trying to use the stock clamps or the one that comes with the kit doesn't work.
High quality part

Probably will require cutting the boot on the smaller opening side. Don't struggle to fit it on your car without seeing if taking a little bit off the side that couples to the air-filter box like I did. I've been told most boots like this will require some modification so don't be thrown by that. Car feels great with it!
