Injen Short Ram Air Intake for 98-02 Accord

Injen IS Short Ram Intake - 1998-2002 Honda Accord 2.3L (F23A1)

Your 6th gen Accord's got 25+ years on it and the factory airbox is restrictive plastic that's cracked or ready to crack. You're not swapping the motor but you want the car to feel sharper and sound better. Injen's IS short ram intake replaces the factory airbox on the 2.3L F23A1 four-cylinder with a mandrel-bent 6061 aluminum tube and a SuperNano-Web dry filter. You're getting a few horsepower at peak and a way louder intake note. The engine sounds alive when you're on the throttle instead of muffled like stock. This isn't going to turn your Accord into a race car. It's an honest refresh that makes a 25-year-old car feel more responsive without breaking anything. And it's CARB legal in California with EO number D-476-3. If you're in California and you need to pass smog, that EO number matters. This intake passes visual inspection.

Here's What This Intake Actually Does

This is a short ram intake. The filter sits in the engine bay where the factory airbox used to be. It's not a cold air intake that routes the filter down into the fender. Short rams are easier to install and they're not going to suck water if you drive through rain or hit a puddle. The aluminum tube's mandrel-bent which means it's smooth on the inside with no crimping. Injen's using calculated diameters (2.5", 2.75", and 3" depending on section) so the tube fits without rubbing on the battery or hitting the hood. A lot of cheap intakes use 3" tubing everywhere and it doesn't fit right. Injen's measuring clearances and picking the right diameter for each section. The SuperNano-Web filter's got way more surface area than the stock paper element. You're getting better airflow and the engine's not working as hard to pull air. The result's a few horsepower at peak and better throttle response through the midrange. The bigger benefit's the sound. You're on the throttle and you're hearing the engine breathe instead of the muffled wheeze the stock airbox makes.

CARB Legal - EO Number D-476-3

This intake's CARB legal with EO number D-476-3. That matters if you're in California. California smogs 1998-2002 Accords (OBD2) and a non-CARB intake fails visual inspection regardless of how the engine's running. This intake passes that inspection. If you're in any other state, the EO number's just nice paperwork. If you're in California, it's the reason this intake exists for your car. A lot of older Honda intakes aren't CARB-certified. You can't legally run them in California. Injen's IS series carries a real EO number so smog techs treat it as legal aftermarket equipment. That's the differentiator that matters most on this platform.

Realistic Power Expectations and Sound

Here's the honest power talk. You're getting a modest gain at peak and better pull through the midrange. This isn't a 20 hp upgrade. The F23A1 makes around 150 hp from the factory. A short ram intake's not going to transform the car. What you're actually getting is sharper throttle response and a way louder intake note. The stock airbox muffles the engine sound. Injen's intake lets you hear it. Some owners want that. Some don't. We'd rather you know what you're buying. If you want serious power out of a 6th gen Accord, the answer's forced induction or an engine swap. Not bolt-ons on the stock F23A1. The case for this intake's honest. You're keeping the factory motor. You want it to feel sharper and sound better. You want a part that's CARB legal so it doesn't cause smog problems. That's valid.

F23A1 Four-Cylinder Only - Doesn't Fit V6

This intake fits the F23A1 2.3L four-cylinder only. It doesn't fit the V6 models (1998-2002 Accord EX V6/LX V6 with J30A1 3.0L engine). The V6's got completely different airbox geometry and throttle body location. This intake won't adapt to it. If your Accord's got the V6 badge on the back, this isn't the right part. This is designed specifically for the four-cylinder F23A1 throttle body and intake manifold. Make sure you've got a four-cylinder Accord before you order. If you're not sure, check the valve cover. The F23A1 valve cover says "VTEC" on it. If your engine bay's got a V configuration with two valve covers, you've got the V6 and this intake won't fit.
