I have a 96 J2 1.6 Gls Elantra, quite impressed by it considering I only bought Volkswagens before. My question concerns the airbox it has a sensor connected to the side of the top of the airbox above the filter element, what is it for? and what would happen if I disconnect it, because I would like to put a ram pipe system in place, I noticed that I have a tube for air running to the bottom by the airdam and another collector by the bonnet,why is it designed like this?

Any advice on what ram pipe system I could use will be greatly appreciated because at the moment it looks quite confusing to me with that sensor and tube, don't want to remove something that will bugger the system.

Thanks in advance

This is almost certainly the Mass AirFlow (MAF) sensor. It measures the amount of air the intake system is currently taking in, and sends this information to the engine control computer, which uses this information and other parameters to figure out how much fuel to send to each cylinder at any given time.
and what would happen if I disconnect it?

Your gas mileage would be horrible.

You probably want to move the sensor, not get rid of it, if you're modifying the intake. Guides I've seen for installing Cold Air Intake (CAI) modifications on the Tiburon provide instructions on moving the sensor and making sure it's connected properly.

Good question. Got pics? Post a URL.

Hm. I'd say "don't bother", because no matter what you do to the intake, you've got only 1.6L to play with. ("There's no replacement for displacement.") There's advice for Elantras on http://www.elantragtclub.com/index/id14.html , and they say that many intakes designed for a mid-late 1990s Honda Accord should work well with an Elantra. HTH,

Don't forget that you would also throw a CEL which means that you would not pass your state's inspection.

CB is posting from .za, where the vehicle laws are a bit different than they are in parts of the .us . But yeah, removing the sensor would result in lots of unburned hydrocarbons in your exhaust.

CB: search for a CAI installation guide on the websites devoted to tuning Elantras. I wouldn't expect too much though; the folks who put an AEM CAI on a 4-cylinder 2.0L Tiburon reported ~7 HP gain at/near 4000 RPM, and you will get less than that since your engine's smaller.
