Rotating MAF
I've searched and found threads on rotating the mass air flow sensor but no pics and no mention of the plastic positioning tab. I pulled the Honker loose last night and tried to rotate the MAF but found the plastic tab that fits in the slot on the rubber coupler does not lay flat and therefore will not seal properly in its "new" rotated position. What am I missing? Thanks in advance! Chris

Callaway strongly recommends that you do not rotate the mass air flow sensor. The molded parts are slotted to allow you to align the parts properly. The orientation of the maf sensor in relation to the throttle plate is critical, as you suggest. Honker design and development included determining the optimum orientation. Rotating the maf sensor will result in reduced performance and possible DTC's.

My gut is to leave it alone after looking at things closer but so many posts claim a SOTP improvement. The position of the rotated MAF would then line up with the butterfly on the TB=smoother air flow. Any insight on that theory? My question, though not actually stated this way is, what did those that did this mod do with the tab to ensure a tight seal? Thanks to all for the replies. Chris

i9have a cold air kit installed that does not have a cut out for that tab so it really did not matter. if you make sure the clamp is tght you will be fine. if it leaks at all you will get a cel
