OEM composite intake...I need a compatible epoxy that will last.

[DanK]

I port intakes and have a customer that needs more cross sectional area in the runners. To do this, I will have to grind into the flap that covers the friction weld seam, so that will end up exposed. That would not be best for airflow so I would like to find an epoxy that will stay in place, resist at least 300*, and decent workable time. It’s a dry intake but, just in case, he will be running E85 (ethanol) fuel and would like the peace of mind it can take some exposure if there were some intake reversion. I’d hope it could be locally available too.

The intake is off a 2013 Ford 3.7L and I’m not sure of the composition. I think it does have fibers in it, but haven’t seen steady signs of this using a carbide burr.

I appreciate any help with this. This customer could really boost my sales if I can do this. Thank You

There is an epoxy that is used in ported cylinder heads to blend the exposed valve guides. Cylinder heads are exposed to much higher temps than intake manifolds so that should be perfect for your application. Contact Luke at 4Pistonracing.com. He should be able to tell you the name of the epoxy that is used (or at least direct you to someone who can).

Could you please share some pics of your work in progress? Also please share the name of the product once you find out. Thanks!

I’ve used 788 splash zone, by Z Spar, in the past. I just thought there may be another recommendation out there. I guess it’s unexplored territory using epoxy on composite intakes for porting purposes.

I believe the intake manifolds are made of Zytel nylon-66 if I’m not mistaken .
