I just received this piece in the mail and figured it would be a 5-10min install. Maybe 20min if i dident already have the new Intake Tube installed and the Air Box removed. I tried to install it on the MAF Sensor right off the bat. It was a very tight fit! But it looked like it would on with some persuasion. I wasent expecting a top notch CNC part as it only cost $20 (even tho Vibrant says its CNC its obviously cast!). So since the fit was so close but tight i figured i would just press it on with a little strength. It just wouldent go! So i filed off the burrs figuring this would help as it was so close! After i spend about 30min on filing off all the burrs and such i tried again. Still to tight but i figured it was better than before i so tried using some strength again. This is such a POS part that even after 30min of work it still wouldn't fit! and i ended up cracking the MAF Sensor. So there goes $480 out the window! But it wasn't so bad i couldn't continue to fit the adapter to it. So at this point i figured the best way to do it was to match the Adapter to the OEM Air Box as the sensor fits that perfectly. So i went to slide the Vibrant over the bolts on the airbox and of course it wouldn't fit! So now i spent another 30min making the off center so it would fit. After that was done i mounted the adapter to the air box and marked it up for grinding. 10-15min here. Than i un-mounted it and started grinding away. half an hour later i mounted it back to the air box to check fitment marked a little more and finish ground it. Now it fit perfectly to the MAF Sensor!

The moral of the story is this is a POS part. Since that day i have ordered a new Vibrant (because the piece of billet would be crazy expensive) and got all the correct dimensions and machined it on my Bridgeport Manual Mill. I have thought about writing a CNC program to make one out of billet but haven't yet.

Does every one have these issues with this piece or what? I dont understand how they sell like crazy and i have never heard of this before! Let me know if you encountered the same thing. I will also modify these pieces for anyone interested. Just PM me!

Thanks, Trever

 

I actually have two Vibrant MAF adapters in my possesion and both fit just fine. You might have gotten one that was the last run of a mold or something.

There are a couple things that could be corrected with the adapter that will make it a MUCH better piece. If you're interested, I'll take a pic and detail it to what I mean.

 

Sounds good brother! PM me with the pic!

 

I've installed quite of few of these on cars and never had an issue. I think you were trying to make it fit in a way it wasn't design to fit. When properly installed it looks like there is still a gap since it doesn't fit flush with the MAF, but it's actually sealed up fine.

 

I had the same thing. But instead of grinding it down, I used smaller bolts. Fits decent now. No leaks whatsoever.

 

I've installed a few of them and the most I've had to do was drill one of the holes slightly larger, +.032" maybe. Oh and file all of the rough casting edges to smooth out airflow.

Use a 120grit flap wheel on a die grinder to round the edges nicely.
