Hey guys this is my first entry so bare with me if its already been answered. Im new to the forum, just bought a 93 318i and ive been lookin through the pages and decided to "debaffle" my air box like lost of people have said. Correct me if im wrong but once u debaffle doesn't that mean you will be taking in hot air, and if so does hot air cause worse fuel efficiency? I already know it will hurt your power but im wondering if it will hurt the fuel efficiency. I would appreciate some responses as well as maybe some CHEAP diy mods i could do to my car cause right now its all stock.

No no. The tube you're refering to is the snorkle. I'd leave that inplace if you're still using the stock airbox. The baffle itself is inside the airbox itself. On the m42 the baffle is huge and it's right inside the airbox. Do a search on debaffle and you can find some pictures.

Anymore questions post um up.

hey liltrig
basically you want to take out your airbox from the engine compartment, and then remove any tubing present inside so now instead of air coming through the tube to the airfilter, the filter now receives air directly from the snorkel.
hope that doesnt confuse u. dont worry i have never done work on cars before and did this a few weeks ago with everyones help here. check this link for the DIYs:
