PRL Front Mount Intercooler for FL5 Type R/DE5 Type S

PRL Motorsports Bar-and-Plate Intercooler - FL5 Civic Type R & DE5 Integra Type S

The FL5 heat soaks like every turbo Civic before it. Run it hard and charge air temperatures climb, the ECU pulls timing to protect against detonation, and power fades pull after pull. This PRL bar-and-plate unit runs a dense 600+ horsepower rated core with 31% more surface area than stock, mounting in the factory location with no cutting and no tune.

Bar-And-Plate Or Tube-And-Fin?

PRL makes both for this car, so this is the decision worth settling first.

This bar-and-plate is the durable, high-capacity choice. Thicker construction holds up better to impacts and debris, and its greater thermal mass means it takes longer to heat soak in the first place. It's the pick for street durability and sustained power.

The tube-and-fin is lighter and recovers heat faster between pulls, but PRL rates it at roughly 75% of this core's durability. It's the specialist choice for road racing where weight and fast recovery matter most.

Straight guidance: for most FL5 and Integra Type S owners, including tuned street cars and occasional track use, this bar-and-plate is the right call. It's more robust, it holds up to daily driving and debris, and it has the capacity for serious power. Choose the tube-and-fin only if you're specifically chasing minimum weight and fastest recovery for dedicated road racing.

What Heat Soak Costs You

The failure is gradual, which is why it's easy to underestimate.

An intercooler that can't shed heat fast enough lets intake temperatures climb. Higher charge air temperature means higher cylinder temperature, which raises detonation risk, so the ECU pulls timing to protect the engine. Pulled timing means lost power.

In practice you get full power on the first pull and noticeably less by the third or fourth. It's worse with spirited driving and considerably worse once you've added power, since you're pushing more air through a core sized for factory output.

A larger, denser core keeps charge temperatures down through repeated pulls, which is what keeps power consistent rather than fading as the session goes on.

31% More Surface Area

The core is where it comes from.

PRL uses a dense bar-and-plate core measuring 28.35 x 4.3 x 7.25", rated to 600+ horsepower, with 31% more surface area than the factory unit and increased internal flow.

Bar-and-plate construction is more durable and more efficient at transferring heat than the tube-and-fin design in most factory intercoolers. More surface area means more opportunity for heat to leave the charge air, and more internal flow means less restriction feeding the engine.

Full-Width Fins Cool The Radiator Too

A design detail that does real work.

PRL extended the intercooler fins to fill the entire width of the front bumper opening. That does two things: it maximizes the cooling area of the intercooler itself, and it channels air through to the radiator behind it.

An intercooler that only covers part of the opening leaves gaps where air spills past unused. Filling the opening means all the incoming air is doing work, cooling both the charge air and the coolant.

True Bolt-On, Factory Hardware

No cutting, no trimming, no fabrication.

It uses the factory mounting points, retains the factory intercooler bolts and hardware, and works with all the original air ducts and shrouds. The billet machined aluminum end tanks maximize flow and look the part through the bumper opening.

Torque to 18 ft-lb. No ECU calibration is required, since a better intercooler improves what the engine already does rather than changing how it's metered.

Silver Or Black

Two finishes, purely a look since the core is visible through the front bumper.

Silver is the traditional intercooler appearance, obvious that something's been done.

Black disappears into the bumper opening, keeping the car looking stock from the front.

Both cool identically. Pick whichever suits the car.

An OEM-Referenced Part

This carries OEM Honda part number 19710-66V-A01, which speaks to how directly it's engineered to the platform. It fits and functions as a factory-position replacement, with considerably more capacity.

Who Should Grab This

This is for the FL5 or Integra Type S owner who wants durable, high-capacity charge cooling that holds up to street driving, debris, and serious power. Bar-and-plate core rated past 600 horsepower, a genuine bolt-on with factory hardware, and full-width fins that cool the radiator alongside the intercooler. If you're specifically chasing minimum weight for road racing, look at the tube-and-fin. For everyone else, this is the one.
