F-150 Manifold Testing/Journey

[grabber yote]

Got mine for $79 shipped. Auction says it’s a take off with 50 miles but when I got it, it looked brand new with no fuel smell

Yeah, these are from new F150's where the owner gets a Roush/Ford Performance supercharger dealer-installed before delivery.

get the '18 intake on Sunday. Will give you all updates on the differences.

I don’t know how you get them under $100 every time i look they are 109 and up.

Crikey...!

This mod must be getting popular? I was seeing these (multiple) manifolds for sale on a regular basis over at eGay for around $80, including shipping; and now there is only one that I can find.

Better get 'em while you can?

Before I found my results I joked about buying all of them I could find and marking them up!!! LOL But..... I'm not that kind of person, which is why I will always be poor.

Impressive mod for daily, street-driven GT's!

Curious, does the F-150 IM require a re-tune? Or can I simply swap out my OEM GT mani with the F-150 mani and drive? I have a Steeda ProFlow CAI and long-tube headers.

 

[Mustang_Lou]

Swap and drive but it appears to get the most out of it (as with any major change) a dyno tune may help.

I got mine from a member on here for jus the cost of shipping ($73.00). Patience is key plus luck. I am paying it forward by doing the same to another member on here when the '18 goes on this Sunday(its already spoken for).

You're pretty confident you'll like the '18 better to have already sold the F150 huh?

Got my 2017 F-150 intake today. It’s brand new. Hard to believe I got it for $79 shipped.

Nice! Just wondering, are these plastic manifolds?

Is it actually possible to "bore out" plastic manifolds? Is only the throttle body section ported, or the runners where it mates to the cylinder heads?

Has anyone actually bored out their F-150 manifolds yet, and if so, what was the end result? Higher upper RPM limit? Even more torque down low?

Yes, the intake is plastic. You can port the intake. I just chose too smooth out the rough casting marks.

Cool, thanks for clarifying.

Wonder if porting the F-150 IM is worth it?

I just got quoted $780 to supply & install the F-150 IM, and have it all custom dyno tuned on my car (before and after dyno runs too). I think I might go for it and see how it goes.

I too was considering the '18 or GT350 IM, but like others on this thread, my car is a DD and I'd MUCH prefer more low/midrange torque than peak HP at 7800 RPM (which I'd hardly ever get to do on the road).
