Default Fernco Hose problems?

What exactly is the problem with a Fernco coupling between the MAF and TB?

I've had mine on for 6 months without cracking of the Lid nor any other problems even after 12 passes on the 1/4 mile.

Why do so many owners complain?

Zero problems here and I have a MTI lid too. I've made roughly 40 passes with it and I've driven about 15,000 miles with no issues.

I couldn't even get the damned thing on! <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

That is... I could get it on the TB. And I could get it on the MAF. But I couldn't get it to stay on both at the same time! <img border="0" title="" alt="[Mad]" src="gr_images/icons/mad.gif" />

Mobe-

It'll fit like a glove if you trim it a little bit.

I think the biggest problem with the Fernco hose is you have to choose a hose that is too large or too small, the correct size would be 3.5 X 3.75... which Fernco doesn't make.

I used an exacto knife and I trimmed the ends of the hose. Now the clamps are flush with the ends of the hose.

I trimmed mine up and made it look all perty like and thought it was the cats ***.... but give it time..... it will crack your lid.... I had about 8,000 miles on mine and perhaps 70 passes and took it off to clean the MAF and the bottom where it attaches to the maf was cracked in 2 places <img border="0" title="" alt="[Frown]" src="gr_sad.gif" />

When I put it on the TB, it sticks straight out. It need to angle up a little to meet up with the natural angle of the lid and maf. Couldn't get it to do that. I even heated it up so it was more pliable.

throw it in the microwave for a good 45 secs to 1 min on a low power level, observe as to not melt it. (done that and now its a badass papaerweight).
assemble your lid to your maf and then slip on the fernco. tighten down all the band connectors and then push the whole assembly onto the throttle body and just really work it on there is the best way to go about it. once on tighten down the last band connector to secure a good seal throughout the whole component.

1 side of the fernco i left alone. The other got trimmed from the middle to the top. It was trimmed on about a 22degree angle . When I was done there was no clamp groove at the very top of the FERNCO. If you look at the stock bellows it should have an angle formed into it from being on there for a length of time. Just replicate the angle by trimming the fernco. I didnt try and bend the fernco, I let the 2 pieces slide together on angle. Then pulled it together with the clamp. If you didnt know any better you couldnt tell mine wasnt suppose to be there.
