Description
The all new BMW E36 (3" MAF) “Birdhouse” Air Intake Heat Shield.
This is a high-quality, air intake heat shield that is a great alternative to the other $400-500 intakes on the market.
Our air intake heat shields are great for those who are just running “cone” filters as they help direct cooler air coming through the headlight, into the intake. As they’re almost fully enclosed, including the bottom, it’s also a great way of preventing water from the road entering your air filter.
This intake was designed and tested in-house, by us, on our 96 328i (M52) and was professionally welded/ assembled by RattyFab LLC. Professional polishing done by QualWorks.
Fitment Notes:
- Fits the 6 cylinder 323i, 325i, 328i
- Designed on a 1996 328i (M52tu) with Silicone Intake Elbow and without ASC+t (All E36 323, 325, 328 use the same factory air intake box position so MAF position should be same across all of them)

- Cannot guarantee fitment on 318ti
- Cannot guarantee fitment on M3
- Does not have hole for the "air box thermostat" found on 92-95 325i
