Dreams do come true

Great product, design, functionality and customer service. Running ITbs alongside a GT35r making all the noises and power, loving it.

Very good customer service.

Andreas helped me with working out what I needed for my bmw to install the ITBs

BMW M30 swapped E30

Got my intake a long time ago when I did the swap originally.

I've been driving it for about 4 years now and havent had an issue with the ITB kit at all.

My car wouldnt be complete without it. It goes very well for its age, not quite modern quick, but for a 36 year old car its more than enough.

ITBs

Got an intake for my E36. Got a lot more power but the sound is what its about.

Fitment

The ITBs are nice, but the carbon plenum didnt fit on my BMW 2002tii as it hits the brake booster. Will return the plenum and run open trumpets only.

smoother idle

Instant throttle response

By giving the intake air a short and direct path into the chamber, the throttle response becomes lightning quick.

increased power

By allowing each cylinder to consume the same and maximum amount of air, your engine can be run at its optimum performance.
