Description

I am an engineer at Harvey Mudd College and I have been experimenting with different intake setups for the 1998-1999 Corolla.  This is a homemade cold air intake that is exactly like AEM systems at a fraction of the price.  The proof that cold air intakes work has already been exhausted, and I have tried everything from hot air intakes, ram air intakes, ram air with coffee can heat shield intakes, and everything in between. This is by far the best setup I have ever done. I have been experimenting with different intake setups for years, and this is my final and best setup yet.

This is better than Regular Intakes because:
Regular intakes pull in hotter air so your reactant mixture is less dense, causing less energy-yielding combustions, thereby lowering horsepower. This is basic chemistry but if you are really curious you can ask me more through e-mail. Regular intakes also have a relatively short intake pipe compared to cold air intakes. Longer pipe lengths have been proven to have better resonance effects and the air is more streamlined when it reaches the throttle body.

This is better than Ram Air Intakes because:
You are still not pulling in true cold air unless you encase it, which is what I did in my previous setup. However, with ram air intakes, you have the filter placed closer to the throttle body and you lose the resonance effects of a longer cold air intake pipe. The ram air enclosed setup also lacks the high end rush of power that cold air intakes provide, because at that high flow velocity, the cold air intakes promote much better flow characteristics as described before.

The filter will not get dirty because: 
The filter is located behind the bumper and to the right, near the fender well. It is completely shielded from debris and water. There is no line of sight to the filter unless you stick your head under the bumper and place your head close to the center of the bumper. It is basically protected from debris and water, but free to suck in air at ambient temperature.

 

Pricing and Components

*Pricing includes shipping to the US!  International shipping extra.

Version 1 components:
2.5" mandrel bent pipe
3 black pipe clamps
washable cone filter
grommets for sensors
Price: $145.00

Version 2 components:
Version 1 intake
battery relocation kit
Price: $195.00

Version 3 components:
2.25" mandrel bent pipe
4 black pipe clamps
washable cone filter
grommets for sensors
Price: $155.00

Note: The Version 1 intake requires battery relocation.  The Version 2 intake comes with the Version 1 intake plus a battery relocation kit.  The Version 3 intake routes around the battery and the battery stays in the stock position. 

The intakes will be sent with the finish you see in the pictures.  You can then paint it or powder coat it if you so desire.

EL Prototypes also makes excellent cold air intakes for Corollas for all years.  Their version for the newer 2000 and on models with the MAF sensor has a welded flange that matches perfectly with the sensor.  Their intakes are usually one or two piece with a nice finish.  Their intake is more expensive, but it also looks better.  You decide for yourself, just don't call them and complain about how I sell the intake for cheaper because they will get mad at you and then they will get mad at me.  Feel free to e-mail me with questions that you may have.
