Don't know if it will make a difference if you say it is for the larger MP122.

They had a small run of the 90mm j-tubes and then had a blow out sale to get rid of the leftovers. i got mine with a wiring adapter for cheap.

Looks like the 90mm flange did come standard on the MP122's.

90mm tube did come standard on 122s and last I heard you could buy the 90mm tubes directly from Magnacharger thats why Richard stopped making them.

If you can’t find the J-Tube your looking for and don’t mind just a little bit of work, you can take the approach I have started along. Yes, you will still have to open up the end of the J-Tube to 90mm yourself and machine the adapter to the full size, but you can purchase a 90mm to 78mm adapter to mate the bolt patterns. You wouldn’t want to just bolt it on and go, as it would serve no purpose to have a restriction of over a ½” in the set-up, but outside the cutting/grinding it does become a bolt on affair.

Thanks all.

So will the 122 j tube work on the 112?

MP112 and MP122 share the same dimensions on the inlet end according to the pdf catalog I'm looking at.

That would be b!tchin if I could mount the 90mm J-tube off the 122 on my 112!

I called magnuson products again . This time I asked for a 122 "J" tube (good idea!). They do have them ( $187.00) . Also confirmed that it fits a 112 blower. Mine is on its way & I'm curious to see if the intake runner is also larger. Dan
