Cold Air Intake For EFI Celicas

    A simple modification is the removal of the stock airbox and filter and changing it out for a free flowing gauze type filter.  Begin by removing the stock air filter, unhook the three clips that hold the cover on.  Once you have the cover and filter out of the way.  Remove all the bolts holding the Airflow meter and Filter plate.  Be sure to save the four bolts that secure the black plate to the Airflow Meter, you will need to use these again.  Next cut about 3/4 of an inch off the rubber air duct where it attatches to the Airflow meter. Then reattatch it with a new hose clamp.  This might take quie a bit of force due to the age of the material, some lubrication will help this.  This is also a good time to clean up the inside and outside of the Airflow Meter. Clean it inside and out with some carburetor cleaner and use a small wire brush on the outside to loosen caked on dirt.


    The next step is to create some type of bracketing to support the Airflow Meter and the new air filter.  I used some aluminum stock that I bought at the local home improvement center for less than 2 dollars.  Plus a few machine screws with matching nuts and washers.  The bends are slitghtly greater that 90 degrees to match the slope of the fender wall.  You will need to remove some material from the brackets to allow them to clear the edge of the intake.  Once you have made these fit snugly around, drill holes to align with the Airflow meter adaptor which can be purcahsed from  Cyberspace Automotive Performance .  Next take the four bolts you removed from the black plate I mentioned earlier,  you will need to cut off the solid washers leaving only the lock washers.  I used a pair of diagonal pliers to accomplish this, just be sure to wear eye protection as the pieces will go flying. Now you can bolt the Airflow Meter, adaptor plate, and the support brackets together as shown above. The brackets will support front to back motion and the intake hose and brackets work together to support side to side movement.  It is amazingly sturdy, I even suprised myself at how well this worked.  In the next picture you can see the 5" S&B Powerstack filter fully installed.  The picture shows it has plenty of clearance on all sides.
