Ram Air Modification For Your Gen 4 Camaro

pic-1Tools you will need:

  1. Saw or Dremel Tool
  2. 200 plus grit sandpaper
  3. 10 mm socket
  4. ratchet
  5. 3″ extension

Expect approximately 20-40 minute install time

Purpose:  This modification will remove most of the bottom plastic on the bottom of the air box. This will decrease the air temperature significantly giving your car some extra horsepower and better air. However, expect your air filter to get dirtier a lot quicker than usual with this modification.

Reminder: Make sure you have the keys out of the ignition. Why? When you remove the sensors from the air box lid assembly, you do not want to start the car. You will set the Service Engine Soon (SES) light. If you do start the car without placing the sensors back in you can easily reset the SES light by following these steps:

    1.  Turn key to the “on” position but don’t start car
2.  Pull the PCM BAT and PCM IGN fuses in engine compartment
3.  Wait approximately 5 minutes
4.  Turn ignition off
5.  Replace fuses
6.  Start the car and then make sure the light has gone off

Comments: At the time we completed this mod we had no other performance modifications. We could tell a noticeable difference in throttle response and additional horsepower. We experienced a slight “whistling” type sound from time to time. Don’t worry about that sound if you experience it. The sound occurs because we removed the silencers on the air box lid assembly.

  1. Thanks for your tip. How would you suggest to stop the “whistling” sound, if necessary ?? Noise is no fun.
    Thanks. Roger

      With the silencers removed, that’s just the nature of the beast. The whistling should only occur sporadically, it should not be a regular occurance.

  2. I have a 1995 LT1 5.7 automatic Z28. How Can I loose the MAF sensor all together. the LS”s do. I actually bought this computer to tune the camaro. Ive tried TunnerPro but cant get it log data. Ive raced dirt track succesfully modified class in 1977 to 79. Ive also raced drag cars succesfully a 1960 corvette Pelfre&Roberts. Im just going to get back to the books. I was talking to a guy who gave good advice and seemed to know his stuff, but computer crashed and I lost all the contacts and data. I deserved it. I know to back up everything. especially when windows is involved.

    • It sounds like speed density is what you’re after . It can be done through a tune. I’d recommend trying to find that guy again, or a shop that specializes in tuning LT1s
