2018+ Honda Accord 2.0T High Volume Intake Gains

Initial Testing Results:

All testing was performed on the same day with ambient temps around 75 degrees Fahrenheit day and moderate humidity. We started all single dyno pulls at 175 degrees, while continuous (back-to-back) dyno pulls start at 175 degrees and end around 205 degrees.

For our first comparison we tested the factory intake system on Hondata’s stock equivalent ECU map versus our High Volume Intake System on Hondata’s stock equivalent ECU map for an apples-to-apples comparison. Run 1 was the coolest (175 degree starting temp) for both setups. We saw a 4 horsepower & 11 ft/lb peak gain and 7 – 10 horsepower gain throughout the mid-range over our Stage 1 Intake System.

Please note that we lost tachometer signal at the top during this run, so we mapped out the plot with torque over engine speed and without torque at wheel speed for representation.

Continuous dyno pulls and testing under the same conditions began to show that our intake produced even larger gains after heat-soak. Run 4 (199 degree starting temp), showed an 8 horsepower & 8 ft/lbs torque peak gain and 15 horsepower gain throughout the top-end over our Stage 1 Intake System.

Please note that we lost tachometer signal at the top during this run, so we mapped out the plot with torque over engine speed and without torque at wheel speed for representation.

One of our main focuses with this intake system was to offer a factory-like fuel trims for optimal drivability and performance. We spent quite a bit of time designing what we determined is the best intake system/MAF housing on the market.

  1. During the runs at 75 ambient temp, what was the IAT temp? It is very important to know the values. please respond very soon.

  2. Very interested in this intake, but I have a couple clarifications to discuss before I order.

    1) why was testing performed with a hondata stock tune? Wouldn’t it be easy to flash back to 100% stock to show customers that it truly works well with a Honda stock tune?
    2) someone else mentioned IATs. Those should also be captured in testing.
    3) there’s mention of gains “over the pro stage 1 intake”, are the charts above a comparison against the stock box & stock intake tube or stock box and prl stage 1 tube? This write up is a little confusing. Can you just do a comparison of 100% stock car w/stock tune vs stock car w/stock tune & new intake?

    Sorry for all the questions, I’m just not seeing the 24hp / 16tq gains claimed on the order page so trying to clarify.

    1. John,

      1.) If we were to flash back to 100% stock we would not have any data logging capabilities to make sure fuel trims are within spec.
      2.) IATs were monitored during testing, and were found to be consistent back to back as the air source is from the same ducting. We no longer have the log files to post for reference.
      3.) We did not have a stock intake hose to compare against, hence why this Blog Post is a comparison between our airbox and the factory airbox w/ Stage 1 hose. Using data from our already proven stage 1 hose (16hp at peak and 18 tq midrange), it is safe to claim 24hp / 16tq peak.

      We would love to do a full stock comparison, but we do no have test platform here. We really look forward to 3rd party results once this intake is on the market as gains could be even more!

      1. Basically it will have lower numbers without the Hondata Stock tune plus most of us will be running tunes. Stock numbers would be lower like 15 to 16 HP 10 to 12 TQ whicvh is still solid but with tune it will go up. PRL has pride they won’t say that LOL!!! They are still Legends anyway! No question it would be lower numbers if flat out stock. Most intakes with low numbers will get higher with a tune PERIOD!

  3. Hi,

    What kind of gains could you expect running the ktuner stage 2 map? The same, more or less? I’m just wondering if turning up the boost negates the gains of this intake as it was on a stock equivalent map.

  4. If you can’t flash it back to 100% stock how do make sure fuel trims are within spec on factory tune with the new intake stage 2 .

  5. *What is the difference in sound on the street between the stock intake and the PRL?* Particularly inside the car. I wouldn’t mind a more aggressive tone but might not want it to get TOO loud/raucous or droning.

    Very interesting and I like it too as a mod that could not reasonably impact the factory warranty. Been driving my 2019 Accord 2.0T 6M for not quite a week and would love to wake it up in a non-intrusive, warranty-safe manner.

  6. Hey Jay,

    While the intake will certainly louder than the stock baffled airbox it is not over intrusive in terms of loudness. It has specifically been designed for the most amount of performance gain. Our airbox features factory like appearance and should not affect your warranty.

    1. There is no Stage 2, we have a Stage 1 and a High Volume Intake. The performance difference are listed here on the post you replied to. Our Stage 1 is essentially just a high flow silicone hose and filter, whereas the high volume is a full intake system with air box.

  7. We are working on CARB approval for our 1.5T Civic intake systems first, then moving over to Accord and Civic Type-R Intake systems. We will be sure to announce and list this in the product listing if/once approved.

  8. Do you source a dry filter that fits this intake? If not, do you have the filter specs/size so I could mount a dry filter?
