Best intake to net mpg

What's the best intake to net the most mpg? Personal experienced would be great.

Does the I/H/E improve mpg?

Re: Best intake to net mpg

I would think the stock intake would allow you to get the best MPG.

More air = more fuel = more power = poorer MPG.

You wont see a noticeable difference with just an intake

Definitely what 98cobra said. I have one of these. Got it for like 40 bucks, and honestly I'm getting a good 29mpg on average with a tank range of between 340-370. (Obviously variable to where I drive.) Granted, 90% of my driving is highway, so that's a big reason for that sort of rate, but still... you can't go wrong with K&N, IF you're looking for better fuel economy.

Custom piping routed so that the filter sits right over the header (the hottest part of the bay). Hypermilers do it I guess.

K&N drop in is your best bet.

Re: Best intake to net mpg

It makes sense. The colder the air is, the more dense it is, the more fuel the ECU will throw at it for a proper mixture. The hotter the air, the less dense...well, you get the idea. I was trying to find a pic of it somewhere, I think it was on a hypermiling forum, lots of Civic guys do it.

Exactly where I was going. Lots of cars, like the Neon, have the intake tube run over the engine/exhaust manifold to increase intake air temp and increase mileage. Temperature and flow are the things to consider for this. You want hotter air, but you don't want it to have a lot of bends and piping or it becomes harder to suck in air. Cheapest and easiest solution is to just clamp a cone filter right onto the throttle body. As far as driving, going slower doesn't necessarily increase gas mileage. The best thing you can do is apply very gentle amounts of throttle. I generally get passed by everyone taking off from a stop light, but I get 30 mpg

Re: Best intake to net mpg

If your car has one of those after market intake kits, stay away from WOT situations and keep the filter clean. If you're oem, get the K&N Drop in and leave it alone. As long as you maintain the 1500-2500 range (never accelerating above 3000rpm) you'll get the best mileage, regardless of intake system.

The I/H/E upgrade will lower your mileage. You will want to hear your "car grunt" all the time LOL

Re: Best intake to net mpg

Probably go with the Type-S intake, same temperature air but with torque gains, should lower fuel consumption.

Re: Best intake to net mpg

I dunno about the whole K&N drop in being that much better. I just had a guy over at the dyno building tell me they tested a Stock vs. K&N filter and noticed absolutely no gains of any kind. Unless the stock Honda filter really sucks balls, I don't see it improving much.

Hell in general I don't see it improving much. You need to spend more money and do more work to see any real gains. Just slapping a new filter on the car is probably only slightly better than slapping a sticker on it.


My opinion, although I welcome rebuttals in the form of dyno sheets.


Anyway, the colder the charge, the better. I've heard some people gain mpg with CAI. Dunno. Never used one. I don't even record my mpg. I used to drive a F-150, the lude gets much better mpg. Good enough for me.

Re: Best intake to net mpg

We rebut on this forum? That'll be a first. The
K&n drop in is a "forget it" mod, 1-2 hp gain is nothing. Just to keep you from changing your filter every 12k at 15-19 dollars. Anything gets better mileage than an f-anything or gm pickup. The better questions are the viscosity of oil in use and keeping the car on Flat roads. There was a whole thread on this, but people got immature about the fuel saving. I'd look it up but I'm on iPhone right now.
