2018 - 2022 Honda Accord
After installation, Mishimoto recommends checking the contents of the baffled catch can every 1,000 miles until a baseline is established. Oil blow-by accumulation will vary with ambient temperatures and driving conditions. It is important that the contents of the can do not rise above the internal baffle
The 2018+ Honda Accord 2.0T is like a grown-up version of its sporty CTR cousin. Equipped with a similar 2.0T, this big sedan knows how to get you where you need to go both quickly and comfortably. It soaks up the road rather than attacking it. While this Accord might be grown up, there are some things it can’t grow out of.
Blow-by is an issue that affects just about every internal combustion engine, including the 2018+ Honda Accord 2.0T. This murky fuel and oil mixture makes its way back through the intake system, coating the top end internals and lending itself to carbon buildup, ultimately robbing your Accord of both performance and efficiency.
Never fear, Mishimoto is here to reduce the risk of carbon buildup in the K20C4 with our direct-fit baffled oil catch can kit for the 2.0T Accord. This kit mounts one of our patent pending 3 oz. catch cans in line with the engine’s PCV system and separates oil and fuel vapors from the crankcase pressure, leaving it behind in the bottom of our two-port can. To simplify the installation, our kit includes two pre-molded hoses, specifically designed for the Accord’s engine bay, along with a robust mounting bracket available in black or Rallye Red. As with all Mishimoto products, the 2018+ Honda Accord 2.0T Baffled Oil Catch Can Kit includes the Mishimoto Lifetime Warranty.
- Direct fit for the 2018+ Honda Accord 2.0T
- Single can mounts in line with the PCV system to separate oil from air using a 50-micron bronze filter
- Helps reduce carbon buildup on intake valves
- Patented (US D884,760 S) billet 6061 aluminum can sealed with Viton™ O-rings
- Installs in under 30 minutes
- Robust, application-specific bracket mounts the can in a serviceable location, available in wrinkle black or red
- Includes pre-molded hoses for simplified installation
- Integrated check valve prevents leaks by keeping boost pressure from reaching the catch can and crankcase.
- Defends intake system and essential engine components from oil blow-by
- CNC-machined aluminum barbed fittings ensure a sturdy connection between lines and can
- Catch can has a 3 oz. capacity for longer servicing intervals
- Internal air diverter increases air turbulence to improve oil separation

EVERYDAY HERO – DIRECT FIT CATCH CAN R&D PART 1 – CONCEPT AND DESIGN
The 2018 Honda Accord 2.0T might not be flying around Metropolis or Gotham punching criminals in the face, but this generation of Honda’s full-sized sedan is taking the heroics of daily driving to a new level. Utilizing the K20C4 derived from the heavy-hitting Civic Type R, Honda ditched the V6 for some efficient and punchy direct injected and turbocharged attitude all under an aggressive new skin dripping with tech.
The Accord’s tenth generation, and all subsequent Honda models, might be teeming with cutting edge technology and on the forefront of the latest automotive trends, but that wasn’t always the case, especially when it comes to direct injection and turbocharging. Where most other manufacturers were taking the plunge into stratifying fuel in the early to mid-2000s, Honda abstained until 2013 with arguably one of the Manufacturer’s best engines, the J35Y4 that’s found in the Acura RDX. Their experiment with force induction is what eventually lead to the K23A1, which also made its way into an Acura’s engine bay.
One could view Honda’s delay to jump into direct injection as a time to perfect the combination of the advanced fuel delivery in tandem with a turbocharger, given that most other manufactures struggled with the carbon buildup that blow-by left behind. Without the fuel injectors constantly washing detergent-rich gasoline over the intake valves, the recirculated oil and fuel took up residence on just about every part of the top-end components in the form of carbon. Leaders in the push for direct injection, like the MKV GTI, Mazdaspeed 3, or E90 BMWs, are all now known for their chronic valve cleanings. Honda is a bit different.
Nothing is perfect. While Honda might have spent extra time to ensure the intake system was safe from the dangers of blow-by, we can safely assume there is still oil sneaking through based on our experience with both the L15B5 and K20C1 Civic engines. Luckily, like we devised for the Civic platform, the Accord is now getting the catch can treatment.
Like the Civic platform, and every Honda before it, the 2018+ Accord also features a front mounted exhaust manifold. This means that all the turbo and intake components occupy the front of the engine bay, giving us plenty of room to work and easy access to the stock PCV line. Even though the Accord was different enough from its younger cousin, and recycling the 1.5T or CTR bracket wasn’t possible, finding a mounting location was still a cinch.
With our engineer’s prototype design complete, we sent our daily driving hero out on the road for a standard 1000-mile test. We’ll see just how much the internal combustion engine’s kryptonite affect our K20C4 equipped loaner 2018 Honda Accord.
EVERYDAY HERO – DIRECT FIT CATCH CAN R&D PART 2 – PRODUCTION SAMPLE AND TESTING
Before, just the name Accord was enough to suggest that this car would keep going. There’s a reason we still see ancient Hondas cruising around today. We want to make sure that the latest version of your daily commuter stays up to those standards. Ditching port-injection and naturally aspirated engines did wonders for efficiency and performance, but the intake takes the brunt of the problems.
The 2.0T Accord might be a grown-up version of the Civic Type R, but blow-by is something that the Accord hasn’t grown out of. In fact, it seems to have only amplified it. Given the additional efficiency features on the K20C4, we expected a reduction in the amount of blow-by making its way through the system. We were wrong.
What did we do to trap all that blow-by, you ask? We gave you a little glimpse of that in the last post, but now we have the real deal. Given the similarities between the Civic and Accord models, our Accord 2.0T kit is set up nearly the same.
Our first inclination was to reuse the CTR’s bracket design to mount our patent pending catch can, but unfortunately the two cars weren’t to that level of similarity. With that, the Accord does get its own specific bracket design, but just like the CTR, will be available in black to retain that OEM look or red for an extra splash of color.
No matter who you are, there’s a fair chance that you always have your eye on the future. We go to work every day to save money or to school to get that degree for some future job. In either case, your 2.0T Accord is the vehicle getting you there. We want to make sure that it can keep up as the years pass.
