2023+ Civic Type R FL5 MDR Front Mount Intercooler Upgrade - FMIC +30HP

2023, 2024 Civic Type R Front Mount Intercooler Upgrade, FMIC, MDR Industries, FL5, K20C, Also Fits DE5 Integra Type S, +29 Wheel HP, +18 Wheel TQ

MDR is pleased to announce their Billet Intercooler Upgrade for the 2023+ Honda Civic Type-R FL5. This intercooler is made in the USA, with machined Billet 6061-T6 aluminum end tanks and a industry leading huge 5.50” core to replace the factory’s plastic end tanks and tiny 2.5” core.

Throughout the testing period, MDR calculated heat transfers for different types of fins, with different fin heights, and fin densities to determine the best combination internal and external fin to achieve the highest heat transfer effectiveness, with the lowest pressure drop. They then designed the core with the most effective fin combinations, which in this case was the bar and plate aluminum core design.

The bar and plate core allows the utilization of the entire envelope space, without larger than core sized end plates as compared to the factory tube and fin. Bar and plate cores are designed to withstand high pressure and high vibration applications. Braze sheets seal the entire row as compared to the 0.125” wide sealing surface of the end plate to the extruded tube on tube and fin cores.

FEATURES:

• Billet 6061-T6 aluminum machined end tanks
• No ECU calibrations required
• Utilizes all factory intercooler mounting locations / brackets
• Core size maximizes the opening on the front bumper
• Notable increase in air density
• 100% pressure tested
• TIG welded
• Assembled in Simi Valley, CA

FITMENT:

• 2023, 2024, and Up Honda Civic Type R FL5 K20C
• 2024, and Up Acura Integra Type S DE5, K20C

'Quick and easy DIY intercooler install on @tiltworx project 2025 Honda Civic Type R! Vehicle is all-stock, fresh off the dealer, with the intercooler as the first upgrade. Awesome feedback on better fuel economy with cooler charge air temperature- estimated 9% gain at 75-80mph drive from Los Angeles to SFO! Exciting things to come for this project.'

DYNO COMPARISON DATA:

After months of testing, street driving, several dyno sessions at different phases, and datalogging, this intercooler has exceeded all expectations, both in cooling and performance gains. Dynos were conducted pre-installation with the factory intercooler and compared with the prototype unit on Specialty Z's dyno. The DYNO runs were done on the same car, on the same day. The only other modification was the Hondata 91 Octane base tune was loaded and present on both the stock FMIC runs and the upgrades FMIC runs. What is noticeable during the testing, the temperature of the factory IC rose as the turbo discharge temperature increased throughout the run, while the MDR intercooler kept the temperature very close to ambient throughout the entire testing phase.

Results and side-by-side comparisons are noted in the graphs to the right.

• Factory Intercooler: 302.40 HP / 334.16 ft-lbs Torque @ 28.03 psi
