AEM Dual Chamber Cold Air Intake - 1992-2001 Honda Prelude

Your 5th or 4th gen Prelude's got a restrictive factory airbox that's choking the H22 or H23. The stock intake uses a small paper filter in a cramped plastic housing that can't flow enough air when you're on the throttle. You're losing power because the engine can't pull the air it needs. AEM's Dual Chamber Cold Air Intake replaces the entire factory airbox with a mandrel-bent aluminum intake tube and an oversized AEM Dryflow synthetic filter. You're getting way more airflow. The dual chamber design pulls cold air from outside the engine bay instead of hot air from around the engine. Cold air's denser which means more oxygen which means more power. AEM dyno-tested this intake and it's proven to add horsepower and torque while improving throttle response. You're also getting a way more aggressive intake sound. The engine sounds louder and fuller when you're accelerating. This intake's CARB legal with EO number D-670-15 so it's street legal in all 50 states including California. The Dryflow filter's washable and reusable. It's good for up to 100,000 miles before you need to clean it. This is what you install when you're done with Honda's restrictive factory intake and you're ready to hear and feel what your H series engine can actually do.

Here's Why the Stock Prelude Intake Is Restrictive

The stock Prelude intake uses a flat paper filter in a plastic airbox that sits right above the engine. Honda designed it to be quiet and to fit around other engine bay components. They didn't design it to flow maximum air. The paper filter's small. The airbox is cramped. The intake tubing has bends and ridges that create turbulence. When you're on the throttle and the engine's trying to pull air, the stock intake can't supply enough. The filter's too restrictive. The airbox is pulling hot air from the engine bay. Hot air's less dense than cold air which means less oxygen per volume. Less oxygen means less power. AEM's Dual Chamber intake fixes all of that. The oversized Dryflow filter flows way more air than the stock paper element. The dual chamber design pulls cold air from in front of the radiator instead of hot air from around the engine. The mandrel-bent aluminum tubing is smooth on the inside with no ridges or sharp bends. You're getting better airflow and cooler air which means more power.

Dual Chamber Design - Pulls Cold Air from Outside the Engine Bay

AEM's patented dual chamber design is what makes this intake work. The first chamber is the filter housing that sits low in the fenderwell area. The second chamber is the intake tube that routes air from the filter to the throttle body. The filter housing pulls air from in front of the radiator where the air's cooler. You're not pulling hot air from the engine bay. You're pulling ambient air from outside the car. The temperature difference matters. Engine bay air can be 150-200°F when the engine's hot. Ambient air is 70-90°F depending on weather. Cooler air is denser. Denser air means more oxygen molecules per volume. More oxygen means more power. The dual chamber design also reduces heat soak. The filter housing is separated from the hot engine bay air so the intake temps stay lower even when you're sitting in traffic or making multiple pulls.

Mandrel-Bent Aluminum Tubing with Gunmetal Gray Powder Coat

The intake tubing is mandrel-bent aluminum. Mandrel bending means the tube is smooth on the inside with no crimping or collapsing. The diameter stays consistent through the bends. That's important for airflow. Crimped bends create turbulence and restrict flow. Mandrel bends maintain smooth laminar flow all the way from the filter to the throttle body. The tubing's finished in gunmetal gray powder coat which looks clean and protects the aluminum from corrosion. The intake accommodates all the factory emissions equipment including the engine breather hoses and water bypass hose. You're not blocking off emissions ports or rerouting hoses. Everything plugs in where it's supposed to. The intake bolts to the factory throttle body and the filter housing mounts to the factory locations. No cutting. No fabricating. Direct bolt-on installation.

AEM Dryflow Filter - Washable and Reusable for 100,000 Miles

The AEM Dryflow filter is a tapered cylinder design with way more surface area than the stock flat panel filter. More surface area means more airflow and better filtration. The filter media is oil-free synthetic material. That's different from oiled cotton gauze filters like K&N. Oiled filters can contaminate your MAF sensor if you over-oil them. Dryflow filters don't use oil so there's no risk of MAF contamination. The synthetic media traps dirt and contaminants while flowing more air than paper. AEM rates the filter for up to 100,000 miles before cleaning is needed depending on your driving conditions. If you're driving in dusty environments you'll need to clean it sooner. If you're driving on clean roads you can go the full 100k. When it's time to clean the filter you wash it with soap and water, let it dry, and reinstall it. You're not buying a new filter every year. You're cleaning and reusing the same filter for the life of the car.

Dyno-Tested and CARB Legal

AEM dyno-tested this intake on a Prelude and validated the horsepower and torque gains. The intake improves throttle response, sharpens acceleration, and increases overall engine efficiency. You're making more power through the midrange and top end. The gains are real and they're repeatable. AEM also engineered this intake to be CARB legal. The CARB EO number is D-670-15 which means the intake is emissions-compliant and street legal in all 50 states including California. You're not going to fail emissions testing because of this intake. Some cold air intakes aren't CARB legal which means they're technically illegal for street use in California and other states with strict emissions laws. AEM's intake passes those requirements so you can run it without worrying about legality.
