A must for e30!

Great set! Very easy to install and makes the engine bay look a lot better than that big bulky restrictive airbox. Now the machine feels better because it doesn't have to breathe through a straw.

  • Makes you happy

  • Quality

K&N You can't go wrong with these filter systems

I use K&N in all my vehicles and have always been happy with the performance and the ease of use and cleaning. The only reason I didn't give that five stars is because I had to make small modifications to the car to make it fit. Otherwise it's a great product and I would recommend K&N to anyone.

Pros
  • a practical item
Cons
  • safety

Difficult to install. There is no noticeable increase in performance.

The product arrived in an open, worn box but all parts were present. However, this particular unit was made in England and came with installation instructions in UK English, as well as a UK tech support phone number. The instructions were vague, as were the illustrations. Photos would be more helpful than rough drawings. I ended up having to forego the instructions and just figure out how to install it myself. Installed, looks fine, but no noticeable performance improvement. All in all, I wish…

  • Ease of use

K&N 57i CAI for BMW m20 engine

This air intake is made for e30 models with six cylinder engines and fits my m20b25 perfectly. The instructions show other options for the m20 engine. This kit does not include a heat shield. The supplied intake pipe brings cold air from the radiator grille area directly to the filter, although no pipe routing specification was used on my engine (build date 10/92). So I "designed" my own best route and how to secure the pipe at each end. Otherwise the installation instructions are excellent and

Pros
  • Solid finish
Cons
  • Damaged
