...and thats why I say to contact me if you have any problems.
You should not have cut it. That ruins it. All you have to do is bend it
out and stretch it with your fingers before putting it on. It stretches.
You can also use hot water on it, as heat makes it more pliable.
An 18 year old girl emailed me that she started to have that same problem because she isnt very strong but that she got out her blow dryer and heated it up and it went right on, easy cheesy.
The MAF is 1/8" to 1/4" larger than the diameter of the coupler (depending on which one you have) but this coupler is designed to stretch over the maf. It is made to do this.
A coupler that stretches is a better option for a tighter fit as the 3.25" to 3" reducer fits too loose. Couplers that are too big then clamped down have a greater risk of leaking.
If anyone else runs into this problem then run the coupler under very hot water. Then take it out, dry it off and grab the side your going to stretch on and pull it outward.
You will see it stretch. Then put it on the maf and tighten it down.
You will notice that one clamp is longer than the other. The longer one is for your maf side of the coupler.
As for it running like shit....your Throttle Body Intake is 3". How is a 3" coupler stretched onto the MAF going to make it run like shit? At no point is a Crab Intake smaller than the TBI. An intake will only flow at the rate of its smallest contriction point and that is not your coupler...its your stock front pipe.
So tell him how it runs now with the intake....
I can send you another coupler but since you cut it, I dont feel intentional damage should be on my nickle. I will do it for actual cost though.
