I have a '53 Ford F100. It has a highly modified Ford 400 motor. I am in the midst of an EFI conversion. I am mounting a Cobra TB on a 4 barrel carb conversion manifold. The TB faces the front of the motor. I bought a Lightning Cold Air Kit from BBK. It has the air box and filter as well as a cast aluminum Inlet Tube. I also have a 90mm MAF.
The MAF will mount to the air box, but the outlet side of the MAF is 4" diameter, and the inlet side of the BBK Inlet Tube is 3.6" diameter. Also there is quite a distance between the MAF and Inlet Tube. I have no connecting tubing.

What is between the MAF and Inlet Tube on a stock Lightning?
Can anyone send me or post a photo of a stock lightning?

 

go to nloc.net, all the pics you want!

 

I found some pictures of Lightning air intake systems. My cast aluminum inlet tube replaces the black rubber tube on the stock setup. I must have all the pieces, but it appears that my 90mm MAF is larger than the stock MAF.


I saw a '03-'04 Cobra at a show today, it had a short piece of tubing connected to the MAF. There was a step in that piece. The large dia. end was connected to the MAF, the smaller end was coupled to a rigid piece of tubing that went to the TB. I need a stepdown from 4" ID to about 3.5" ID. I can get a piece of straight tubing or bent tubing in 3.5" ID to run to my BBK inlet tube.

What size MAF does a '03-'04 Cobra use? I am only asking this question here because I could get lucky and get an answer. Otherwise I will try a Cobra forum.
