How to Make a Cold Air Intake DIY style!

DIY Cold Air Intake

Vehicle performance is everything for some car owners and they’d give anything to achieve that. But of course, being practical when it comes to vehicles is also one way to achieve the desired performance. It doesn’t always have to be expensive as one can always get himself a cold air intake or better yet, make one with a DIY (Do-It-Yorself) cold air intake. This device is one of the inexpensive ways of boosting up performance.

But before looking into details on how to make one, one has to be knowledgeable about the nature of the device. As mentioned, it boosts vehicle performance. It does so by taking in a colder or denser air from outside the engine bay (not from under the hood which is what the stock air intakes do). It also absorbs great quantities of cold air as its main goal is to supply more oxygen for a more efficient combustion.

Now that the functions of cold air intakes are established, below are the steps on how to make a DIY cold air intake. These would be helpful for those who want to try to unleash the mechanic in them.

First, one has to go to the store and buy the needed tools which are cone filter with an inlet diameter of about 3mm, a rubber hose that’s about 55mm, a flexible heavy truck 3mm exhaust tubing, 4-3.5mm clamps, and a high temperature paint (which is optional). The tools that one would just need are hack saw, sockets and some wrenches.

• First thing to do is to remove the stock factory air intake installed.
  
• Cut the stock air intake hose, get a heat gun and heat the rubber hose. While doing so, work the tubing into it. Get the clamp and put it over the rubber hose’s edge.
  
• After that, take it and bend it the way it is needed to be bent. Be sure to leave as much space as possible between the exhaust manifold and the tubing (at least 1-2-inches). Then, remove the bracket that holds the factory intake in place. Remove the bolts that hold it and keep them somewhere safe. This will provide room to work on. Make sure that the gap between the road and the tubing is about 14-inches. Also note the length of the filter – if it is longer, make the pipe smaller. Measure the ground and the tubing using a ruler then cut it across.
  
• Then start working on the air filter on to the tubing. Use the heat gun to warm the rubber part of the filter with then continue sliding it on the tubing. After that, place the clamp on the edge of the air filter’s rubber part and secure it down.
  
• Support the tubing with the bracket that was holding the air intake before and bend it so that it becomes parallel to the tubing. One could also heat it so that it would be easier to bend it with a plier.
  
• To secure the cold air intake in place more, reinstall the bracket and get the 2 clamps over it and the tubing. Then jack the front end of the car up, then put the clamp through the hole in the frame and around the tubing. Another reminder: don’t forget to securely tighten the clamp on the hose of the air intake on the throttle body. Then, check that all clamps are tightened down.
  
• Now, it’s all set! Take the car for a drive and feel the difference that the cold air intake provides.
