Installing new Air Filter
Posted 08 January 2004 - 11:17 PM
My 86 XT-GL uses a vane style MAF. I just picked up a nice, large, conical air filter off eBay ($4) and a heat shield to go with it ($10). What do I need to to in order to affix the new filter to my engine, given the vane style MAF?

The one problem you are going to have (unless you somehow use the existing air box) is supporting the MAF. As it is now the air box is the support. You can add a bracket down to the frame.
You will need an elbow with a sharp 90 deg turn to miss the inner fender. If you would like I can send you some pictures of my varrious creations or goto http://www.subspeed.com/
He sells a rather expensive adapter, but it may give you an idea.
Here is an experimental version but the MAF to turbo pipe needs changed as shown to set the MAF back.
You can see the bracket though.
One small warning though, these style MAF's do like a volume of air in front of them. That is why the air box is configed like it is, I believe.
I learned this using the above prototype. My filter is now mounted in the area between the inner fender and fender.
Hope this helps some.

I have seen adapters at autozone that will bolt on to our MAFs, but I don't know how well they will seal againct the square/rectangular Vane style.

Just the piece that the filter connects to. Mine's a little black plastic piece. But, if you have the square opening, the Sentra MAF adaptor won't work well.

If you would care to learn more about the two different types of air flow sensors please see
You would need to change the ECU. wiring harness and various sensors.
A wee bit more involved than bodging an adapter for your new filter.

Anyone here have experience with adding a cone filter to a vane MAF?
