JM Fabrications Intake Manifold

Anybody running this Intake Manifold? How is the fitment? How is the custom made dipstick? Any cutting or extending of the hoses required for installation? Any pics installed?

Here is the manifold I am talking about. I like the fact that they give you a dipstick tube with the manifold.


EVO 7/8/9 Sheetmetal Intake Manifold
[EVO-INTA-00]$625.00

In tradition of our high quality power proven, yet quite affordable products comes the latest option for Mitsubishi Evolution 7/8/9 intake manifolds. Just as our DSM and SRT-4 manifolds have increased power on many of customer cars, be certain that the same will happen with your Evo and this intake manifold. Introducing our aluminum sheetmetal intake manifold. These are hand made, TIG welded from high quality 6061 T6 aluminum. The flanges are all CNC machined and surfaced for precise fitment and a leak free seal. Each plenum is press bent to reduce the number of welds which will assure maximum strength under high boost applications. The plenum measures 16" long by 4 1/4" deep, the plenum also features a 1" taper design to even out the airflow, with a runner length of 5 1/4". Velocity stacks are CNC machined into each plenum bottom to improve airflow by 10-15%. The vacuum ports are placed on the underside of the plenum for a clean professional look. They are available unpolished or with a mirror like polish. Each manifold comes with a custom made SS dipstick tube. Some modifications to your upper intercooler pipes may be needed, as this manifold sits down a lot lower then stock. If using the Accufab and other aftermarket throttle bodies, please note that the throttle cable and TPS sensors may need modifying. This manifold will also eliminate your EGR system so if you are not running a stand alone engine management most likely you will receive a CEL due to the eliminated EGR. An ECU flash is in the works to eliminate this error code. Expected gains can be anywhere from 10-45 HP depending upon your setup! Why believe hype, when you can see actual dyno results that this manifold works. A local Evo specialist shop nearby in the tri-state area did some testing on one of their customer cars and we were more than excited when we saw the results. The test vehicle was an ’06 Evo 9 MR, stock bottom end, Turbo Trix Racing 280 cams, 1000cc injectors, Walbro pump, TTR 50 trim kit & IC piping kit, SMC alky kit being ran on all runs and AEM EMS for engine management. The runs were done back to back, same day—same dyno—same boost (32psi), with only the intake manifold being swapped out. Prior to our intake manifold install, the car was fine tuned to an impressive 494.5hp, 441.28 ft/tq which is extremely rare to see a 50 trim car making such power. With our intake manifold bolted on, the car spun the rollers to an even more impressive 512.39hp and 461.4 ft/tq ! Horsepower was ABOVE the stock intake manifold graph virtually the entire run too, starting at 3500—just see the graph below for yourself. You may think 18 peak hp and 20 ft/tq isn’t really all that much, but also keep in mind that this car was practically maxed out on it’s current setup. At mid-range RPMs the gains were even larger increasing power by 41hp! Put this on a 35r or larger turbo’ed car that loves to pump a lot of volume and breathe up top and expect 1.5-2 times those gains! We’ve seen it with the DSM’s, and know this is possible. So if you’re ready to step it up and make the most out of your current Evo mods, then consider swapping out that tiny restrictive intake manifold for a JMF sheet metal intake. It’s proven power!

Bean supplied the dyno chart to use.

Fitment of the manifold is amazing. The addition of the custom dipstick tube makes life SO much easier. The manifold CAN be used with the stock intercooler pipes by flipping the front 90* elbow. It can also be used with most aftermarket pipe kits with little to no modification required. I installed the manifold on my nearly stock Evo and felt amazing gains (judging by the butt dyno)....especially in the upper RPMs were the stock manifold dies off. Add a bigger turbo to the mix and the gains will be exponentially higher. I've had JMF manifolds on all of my DSMs and Evo..back from the days that he was making them in his garage. Never had one single problem with them.

Could you please post a pic of this? What did you do about the EGR and hoses? Can you use the stock ECU?

I would buy this manifold if I can use the stock upper intercooler pipe, sensors, and not too much modification to the hoses.

Anything else?

Their manifolds have a excelent rep in the DSM world. My wife bought me a exhaust maninfold heat shield from them, and even on this simple cheap part the attention to detail was amazing

I just bought myself a late Christmas present and am now eagerly waiting for my JM Fab intake mani to show up

I'll see if I can find the pic I took. To be honest you're not going to get the optimum benefit of the intake manifold if you're using the stock upper intercooler pipe though.

As for sensors, the EGR provision is removed, as with every other aftermarket intake manifold. Yes, it can be used with the stock ECU.
