I have the Euro spider set up and i am having a hard time finding something to make an adapter with. i need a 3.75 pipe to slip in to the Bend (oring) then go out about 4-5 inches and ill have to adapt it to a Filter. I'm looking at a K&N oval style. but finding that 3.75 pipe is killing me. if i do find it, i can only get it in 4 foot sticks....... right now I'm looking at getting a quote to have something machined down to that size....

hummmmm.... any ideas on what could be used? even plastic could work.

Jake, I'm having a hard time trying to figure out what part you are looking for. Is this spider to TB, U to AFM? Do you have a pic? Thanks,

robot808

Wait, are ditching the AFM? Looking for a tube that you can run out of the U?

Hmmm
I too do not know what part you need.
I am also running a Euro Spider and TB with the AFM

But try www.spectreperformance.com

UGH. my bad... on my Mega squirt install i do not need the AFM. and i have no room for the stock air box (i did get the euro MAF with the intake from england).

i have tried Spectre but it goes from 3"-4". if worse comes to worse i can take the U out and weld on a pipe... but id rather not. I'm not running boost.


so something like this.... this is 3.5 exhaust pipe... almost but not enough....

robot808

Any chance you could find a rubber coupler that would go around the outside of the U?

How much is the 4' length of pipe? I'll be in the same boat here shortly on my motor with the MS install. If you could have a bunch of the parts made and resell them, it may be worth your while.

I'm unsure if the up-elbow is the same size on mine.

Could use use a MAF as a slave part and build from that?

robot808

He's eliminating the barn door AFM.

don't even have a MAF. i think what i will end up doing is taking the U out, and welding to it.... if i can get it out without taking the spider apart..... :-) maybe... i might end up just tacking it, then using epoxy. that way if for some reason i sell the intake or something, i don't destroy a euro part.

Have a welder weld 3.5 aluminum tube to the U.

First of all I think it is not pipe you are looking for, but rather tube. If I understand, you need a piece of tubing that is 3.75 in (od) to slip into the O-ring and then extend outward about 4 to 5 inches. Is that correct?

If you can, however, find a piece of aluminum pipe that is 3.5 inched id and with thiick enough wall, it can be machined down to the 3.75 od you need. Or, you can find 4 inch tubing that is thick enough wall it can be machined down to 3.75 od. It sounds like the upper end that is going to connect to the filter is not a critical size.

I will look around and see if I can find a 4 inch tube with thick enough wall and machine it down for you. How long does the turned down section need to be? What are you going to do about connection to the filter housing.

looking at about 5/8 inch for the machined lip. another idea i had was create a 3.75 OD "Ring" and weld it to a 4"OD round plate making a flange. then i can weld on a standard 4" pipe. then create what ever i need to fit what ever filter it is i choose (filter inlets i have found are 3.8ID and 3.5 ID.)

I take a tube, run a cut down it, then weld in a strip to make it the true 3.75" as I have run into this lots.....
