How to Install a Performance Intake Manifold and Replace Gaskets (Dyno PROOF)

  • Published on May 29, 2018
  • Learn how to replace an intake manifold and intake manifold gaskets in your car or truck. I am upgrading my intake manifold from a non PI intake to a PI performance intake which will hopefully add some Horsepower and Torque! I also show you how to install a water pump, and how to tap the intake port for a coolant temperature sensor.
    Performance Intake:
    Extendable Ratchet:
    Torque Wrench:
    3/8's Tap and 37/64" Drill Bit set:
    Center Punch:
    Heater Tube and Fitting:
    Intake Manifold Gasket:
    No Spill Coolant Funnel:

    I really admire the work you put in all the videos. I check for your new videos almost daily and always wonder what takes you so long. Everytime I see the new video I'm like "okay, this was worth waiting". The work you have to put in repairing the car and in addition to that, the work you have to put in moving and placing the camera so every bolt you touch is visible for the viewer and finally editing the video the way you do it (every transition, every splitscreen, all the bolts to mark and these things you do with graphs) must take hours and hours. I really appreciate it and hope that you'll keep doing such a great videos. Even though I don't even have a car, I always enjoy your videos, so one day I buy myself a car, i can do it at home just because of you. Thank you!

      Exactly, he makes everything presentable and easy to learn, no nonsense and bad camera angles, really inspired me to learn more and work on my own vehicle.

    Your dog stood up and took a big fat damn look at your engine bay and he probably saw the crack in your intake manifold

    I really like your videos and the effort you put in it.
    But I always ask myself the question: How do you got so much knowledge about cars and how do you keep track where everything goes in?
    Are you working as a professional mechanic or is this just a hobby?

    When doing pipe threads, you only go 3/4 of the way up the tap. If you go all the way, it won't seal properly.

    I think that ur mustang with the stock intake you could make alomust an 200 hp coz when ur on the road and drive you in take takes more air in and forces air in the engin thus procdusing more hp

  • dntlss

    Excellent video as usual, a couple of things if i may add,older 4.6s had a longer snout water pump,the newer ones have a shorter pump,that first water pump you bought is actually much better than the other stock one you picked up,all you have to do to get that one to work (the longer one) is to replace the pulley, the reason the pump is better is because it has a sealed impeller (the ring attached to it) vs the open impeller of the old design, no biggie,it still works.

    On the water pump o ring they just recommend putting a little coolant on it since coolant is oily it works in helping the new seal slide into the housing but if you have some of that "gunk on a brush" that works too, i say this for the guys that dont have any grease they can get by by using fresh coolant and last but not least, since you had the water pump out you should had replaced that nipple instead of just the o rings,those new black nipples (no jokes here,lol) are real nice and not all corroded and nasty like the old ones, just pop the old one out and hammer in the new one and your done, i have probably done a dozen of these intakes for myself and friends so I'm no stranger to them,excellent video Chris and the quality is second to none,you are truly the best.

    Maybe someone in the comments will know this but, if you install a performance intake or short ram intake, would you wanna upgrade your intake manifold too?

    ChrisFix, your videos used to be so good and relateable. Too bad your new videos have gone beyond the abilities of the average DIY'er. Time to move on.

      These are still very doable by yourself. These videos are used as a reference, and show the process so you know the theory of this project.

    It be nice if you did a manifold job showing how to on a old truck like a 1979 Ford F-150 and place a 2 carb on a 351m engine and show how to hook up the fuel lines and how to hook everything up on the intake manifold it be really useful for me and I bet others who have old vehicles wanting a dual carb setup and has a 351m engine or the predecessors of it.

    If im doing any kind of aftermarket work and if it dont fit im not going to install it. Not going to do any more modifications to make an aftermarket part fit. That smells like trouble.

    I was siphoning my overflow tank the other day during a coolant flush, and I got a couple drops on the tip of my tongue. Turns out, they add bittering agents to coolant now; the taste was horrific, and I was trying to spit it off for about 10 minutes. 0/10, would not recommend.
