The K&N 69-1511TWR is a 69 Series Typhoon Cold Air Intake built specifically for the 2023-2025 Honda Civic Type R FL5 and 2024-2025 Acura Integra Type S, both running the 2.0L K20C1 VTEC Turbo. The 69-1511TWR replaces the factory airbox with a mandrel-bent aluminum intake tube in K&N’s signature Wrinkle Red finish, a K&N RP-5113 high-flow cotton gauze filter with carbon fiber top, and a steel heat shield enclosure. Dyno-proven gains of +12.04 HP at 5,494 RPM and +17.6 lb-ft of torque back up the design. Installation takes approximately 60 minutes with basic hand tools. The KNN69-1511TWR is made in the USA and covered by K&N’s No-Hassle Lifetime Limited Warranty (10-Year / 1,000,000 miles). Not legal for sale or use in California on any pollution controlled motor vehicle.
Why the 69-1511TWR Outperforms the Factory Intake
Honda engineers the factory airbox around packaging constraints, not peak airflow. The restrictive OEM intake tube and paper filter choke the K20C1 turbo precisely when you want it breathing hardest. The 69-1511TWR eliminates both problems: a mandrel-bent aluminum tube maintains consistent inner diameter through every bend, eliminating the flow-robbing crimps found in stock plastic tubing, and the RP-5113 cotton gauze filter flows up to 50% more air than a conventional paper element while trapping particles down to 99% efficiency.
K&N’s dyno testing on the FL5 Civic Type R confirms the 69-1511TWR adds +12.04 horsepower at 5,494 RPM and +17.6 lb-ft of torque over the factory intake. Testing was performed on a wheel-based dynamometer with SAE correction factors applied, comparing the same vehicle before and after installation on the same day. The steel heat shield enclosure mounts in the factory airbox location and isolates the filter from underhood heat, protecting those gains in stop-and-go driving and repeated hard pulls on track days.
69 Series Typhoon Design: Wrinkle Red Aluminum Tube and RP-5113 Filter
The intake tube in the 69-1511TWR is mandrel-bent aluminum finished in K&N’s Wrinkle Red powder coat. Mandrel bending preserves the tube’s full inside diameter through every curve, unlike crush-bent or stock plastic tubes that partially collapse at the bend and restrict airflow. The aluminum construction also dissipates heat faster than plastic, keeping the incoming charge cooler.
The included RP-5113 air filter is a round tapered cotton gauze element with a carbon fiber top. It measures 5 in. flange ID, 6.5 in. base OD, 4.5 in. top OD, and 5.625 in. tall. K&N’s oiled cotton gauze media captures particles down to 99% efficiency while allowing a dramatically higher volume of air to pass versus a disposable paper filter. The RP-5113 is washable and reusable for the life of the vehicle.
Steel Heat Shield Enclosure Every 69-1511TWR kit includes a steel heat shield that encloses the RP-5113 filter in the factory airbox bay. The enclosure uses existing factory mounting points, keeping the install clean and reversible. By sealing the filter away from underhood heat, the heat shield maintains a cooler, denser air charge entering the K20C1 turbo inlet. This matters most on track days and in traffic, when engine bay temperatures are highest and the potential for heat soak is greatest.

FL5 vs. FK8: 69-1511TWR vs. 69-1505TWR
K&N produces separate Typhoon intake kits for each generation of the Civic Type R. The 69-1511TWR is the correct intake for the FL5 (11th Gen, 2023-2025). The 69-1505TWR is the correct intake for the FK8 (10th Gen, 2017-2021). The two kits are not interchangeable. Both vehicles use the K20C1 engine family, but the airbox routing, tube geometry, and mounting points differ between generations. Ordering the wrong kit will result in a fitment failure. If you own a 2017, 2018, 2019, 2020, or 2021 Civic Type R, you need the 69-1505TWR, not this kit.

Frequently Asked Questions
Is the 69-1511TWR legal in California?
No. The K&N 69-1511TWR does not have a CARB Executive Order (EO) number and is classified as California Restricted. K&N’s official product page states it is “not legal for sale or use in California on any pollution controlled motor vehicle.” This product cannot legally be sold to California-registered vehicles. Customers in all other 49 states can purchase and install this intake without emissions-related restrictions. If you need a CARB-legal intake for the FL5, you will need to look at a competitor product that has received a CARB EO for this specific application.
Does the 69-1511TWR fit my 2017-2021 Civic Type R (FK8)?
No. The KNN69-1511TWR is engineered exclusively for the FL5 (11th Generation) Civic Type R, covering model years 2023, 2024, and 2025. The 10th-generation FK8 Civic Type R (2017-2021) has different airbox routing and mounting geometry. FK8 owners need the K&N 69-1505TWR, which is the correct Typhoon intake kit for that generation. The two kits are not interchangeable, even though both vehicles use the K20C1 engine family.
Does the 69-1511TWR fit the Acura Integra Type S?
Yes. The 69-1511TWR fits both the 2024 and 2025 Acura Integra Type S. The DE5-generation Integra Type S shares the FL5 Civic Type R’s K20C1 engine and intake configuration, making this the same correct kit for both vehicles. Confirm you have the Type S trim with the 2.0L turbocharged engine, not the standard Integra with the 1.5L turbo, which uses a different K&N part number.
What are the dyno-proven horsepower and torque gains?
K&N’s dyno testing documents +12.04 horsepower at 5,494 RPM and +17.6 lb-ft of torque on the FL5 Civic Type R. Testing was performed on a wheel-based dynamometer before and after installation on the same vehicle on the same day, with SAE correction factors applied for standardized conditions. Five runs were taken before and after; the highest and lowest modified runs were excluded, and the best average gain was published. Actual results will vary based on vehicle condition, current tune, and other modifications.
Will the 69-1511TWR void my Honda or Acura factory warranty?
Installing an aftermarket intake cannot by itself void your factory warranty. Under the federal Magnuson-Moss Warranty Act, a manufacturer must demonstrate that the aftermarket part directly caused the specific failure being claimed before they can deny warranty coverage on that component. Honda or Acura cannot simply void your entire powertrain warranty because you installed the KNN69-1511TWR. That said, if you experience a warranty claim related to the intake, air filtration, or MAF sensor, that specific claim could be evaluated on its merits.
What is the K&N Lifetime Limited Warranty and what does it cover?
The K&N No-Hassle Lifetime Limited Warranty covers the KNN69-1511TWR for defects in materials and workmanship for 10 years or 1,000,000 miles, whichever comes first. Coverage applies to the original purchaser only and is non-transferable. The warranty excludes damage from transportation, improper installation, failure to follow instructions, racing or competition use, and normal wear. If K&N cannot repair or replace the product, they will refund the full purchase price. K&N customer service reportedly ships missing or defective components overnight.
What tools do I need to install the 69-1511TWR, and how long does it take?
Installation requires only basic hand tools: flathead and Phillips screwdrivers, 8mm and 10mm sockets, a ratchet with extension, and pliers. No welding, cutting, or drilling is required. K&N rates the install at approximately 60 minutes for most users, and real-world FL5 owner reports confirm this estimate. Difficulty is beginner to intermediate. All mounting hardware is included in the box. You will need to transfer your factory MAF sensor to the K&N intake tube during installation.
Does the 69-1511TWR require any electrical harness modifications or ECU tuning?
No harness modifications are required. The factory MAF sensor transfers directly from the OEM airbox to the K&N intake tube, maintaining the stock MAF signal to the ECU. All factory connections for the crankcase vent (CCV) and EVAP system are retained using fittings built into the K&N intake tube. No ECU tune is required for the intake to function and deliver the advertised power gains, though a tune may help further optimize the engine’s response to the increased airflow.
What exactly comes in the box with the 69-1511TWR?
The 69-1511TWR ships as a complete kit including: the mandrel-bent Wrinkle Red aluminum intake tube, the RP-5113 cotton gauze air filter with carbon fiber top, a steel heat shield enclosure, one black silicone hump coupler, three stainless steel hose clamps, all mounting hardware (brackets, bolts, washers, rubber-mounted studs), K&N filter oil, installation instructions, and a K&N Lifetime Limited Warranty card. No additional hardware purchases are required for a complete installation.
Is the RP-5113 filter included or do I need to buy it separately?
The RP-5113 filter is included in the 69-1511TWR kit. When it eventually needs servicing, the RP-5113 is available as a standalone replacement filter. K&N cotton gauze filters are washable and reusable; they typically require cleaning every 50,000 miles under normal driving conditions, not replacement. Use K&N’s own recharger oil kit for cleaning to maintain filter efficiency ratings.
