Removing Honda CRX Stock Air Intake & Resonator

Introduction: Removing Honda CRX Stock Air Intake & Resonator

About: I build things

The resonator box and intake extension are basically made to quiet the intake, they also restrict air flow into the engine. To make things worse the extension piece is positioned right on top of the header which means it’s basically sucking in hot air.

Removing the whole assembly isn’t going to do a huge amount of anything performance wise, but since I have to wait until after my engine swap to add a proper cold air intake this is the best I can do.

Since I had the whole bumper off to fix a headlight anyway, I decided to remove everything.
Taking off the bumper is a pain in the ass and I haven’t done a write up for it yet, but I will eventually, until then you’ll have to figure it out yourself.

Step 1: Step 1

The extension piece is the thing the arrows are pointing to
While it’s off you can always get a lovely assitant to carefully scrape nasty bugs off your radiator. Be prepaired to answer questions like; “How big are the UNUSUAL bugs in B.C.?”
“Jebus what the Heck is that?”

Step 2: Step 2

The extension piece is bolted along the top of the radiator by two bolts (I’m pointing to the right one their’s another one off to the left)

Once those bolts are off you can just pull the extension out, I put the bolts back into their holes, just in case I need them for something later

Step 3: Step 3

The resonator box is under the passenger side headlight, it’s bolted in with two bolts; undo those and you can pull it out of the filter box.

Step 4: Step 4

Throw those pieces on your driveway and your done.

    The resonator actually makes your car more powerful. It provides a expansion chamber for pressure waves to dissipate when you suddenly close the intake valve and other back pressure waves from the cylinders etc. so that when the engine does need fresh air again it's not fighting the back pressure waves. But whatever, just disregard the hundreds of engineers and people that are involved in designing a car 'cause I'm SURE you can build a car from scratch if you wanted to.

    This is a very informative blog. It provides techniques and information with regards to a proper and safe cold air intake of your engine.

    Before I built my corolla, the stock intake didn't have a resonator. It was seriously no where close to having real horsepower. :-D
