Air Intake for 2017 MDX
I would like to upgrade the factory intake for my wifes 17 mdx, but all I can find is drop in replacement filters.

Time for some DIY action!!!
you can do a free mod by chopping off the intake resonator and relocating some piping or you can spend about $100 to custom make a 4" intake, which will out perform any of the branded intakes on the market,ie; AEM, K&N. https://acurazine.com/forums/3g-tl-p...intake-882902/ Due to all the hype on 4" intakes on the J30 7th gen accords(TL's little brother), I will be putting one on my TL-S. Not sure how many other TL-S are running this setup, but a quick search showed its mostly accords. Obviously this is for people who are interested in function over form as this WILL outperform the very popular AEM V2 cold air intake. I ordered a 4" 90 degree aluminum pipe, 3"-4" coupler, 4" clamps, and a 4" K&N filter. Parts should be here in a couple days and I'll post some pics and a small DIY if you guys are interested. Here is a pic from an accord over at v6.p forum to give an example: https://i157.photobucket.com/albums/...e/DSC05343.jpg Parts needed: 3x 4.25" clamps 1x 45 degree 4" coupler 1x 3"-4" reducer coupler 1x 4" piping, 90 degree bend, centerline radius 6", tangent length 8" 1x 4' K&N filter RF1015 everything is available through ebay, cost me $112 shipped. For the piping, I cut off 2" on 1 end, and 6" on the other end. In retrospect, 1" cut instead of 2" probably would have been better but it'll still work. Here's the setup I got in the mail yesterday...pretty much what you're looking for lol https://i239.photobucket.com/albums/...ps871bebee.jpg |
don't do that in a state that inspects for smog. Know several folks who have gotten expensive tickets modifying the intake on late cars, and had to put it back to factory. They don't tell you that when they sell the kits, it is usually on the back in fine print - "off road use only."

Why on earth do you think it needs one? The last thing I would say the MDX needs is more power (which I doubt you will even tell the difference with an intake). I can easily break my front tires loose on the stock engine at launch.
the MDX weighs more than 3500lbs and the DIY 4" intake at most, makes about 8hp |
Don't do it. Waste of time and money. Not going to improve performance... And hotter intake charge will hurt power, if anything.

I agree- it comes with a cold air intake stock, so you're unlikely to see gains. You could eliminate some of the features designed to eliminate intake noise, but I'd be shocked if you saw more than a 1% gain. Also, gauze filters flow more air through a MUCH smaller surface area as they have fewer, shallower pleats than paper filters. That means they not only let in MUCH larger particles, but they also clog up quicker. Even fresh and new the flow rate improvement is marginal at best.
Modern cars, particularly higher end ones, have pretty well designed intakes. Even the exhausts are good now days, although jam-packed with catalytic converters and such. Unless you're making other serious mods, like a turbo charger or some aggressive cams, there's nothing to really be gained in intake, exhaust, and ignition tomfoolery now days because things are already so good from the factory. |
I use drop in K&N filters on my other acuras just for convenience since it goes up to 50k miles supposedly. Has anyone actually ran a KN up to 50k?
