RK Titanium Ram Air Intake System Say hello to the RK Titanium ram air intake system for the GR Corolla! Made out of CP grade 3” (oem equivalent maf) or 3.5” (oem plus maf, will require a tune) titanium tubing; these systems will flow much more then oem as well as many competitors on the market. A one piece pipe that connects on the second junction on the oem inlet providing more replacement distance and a larger diameter inlet then anyone on the market. We designed our heat shielding and air duct lower and larger to encompass more fresh air into the pocket from the front bumper. Our large diameter oem element cone air filter is fed fresh air from the oem snorkel inside the bumper. We use a 2.5” titanium tube compressed on one end to match the oem bumper snorkel. This effectively directs all of the air from the bumper duct directly to our air filter placement out flowing others on the market. The directed angle off of our duct ensures equal amounts of air blanket the filter for cool suction. Why didn’t we use box design? At lower speeds or any situation where limited airflow is passing through the front bumper or more specifically the exact spot that the snorkel is located, an intake box would be suffocated with enough airflow thus starving the larger diameter system. The design of our heat shielding and open style box effectively blocks out radiating heat from the engine and trans side of the engine bay. This allows for both an amplified intake sound as well as not choking up the intake system under low speeds. Will water leak in from the circuit hood duct onto the filter? No. We water tested by spraying a hose around the duct on the hood to find no direct water contact with the filter below. The design of the shielding allows any collection of water to drain out the bottom through purposed seams while the filter itself will stay dry. Will I get a check engine light? Our good friends over at 555 Engineering have figured out the fix for this for most cars. The common PCV cel code that comes with most aftermarket intakes is a simple issue with the oem scaling for the sensor. Toyota has issued a TSB for this which can be flashed at the dealer if the light is present. The issue with this is that they may or may not flash your car to update the scaling if you have an aftermarket intake. The guys over at 555 have done the work for you and provided a detailed writeup on how to perform the update yourself! We commend them for continuing to develop and help the community on this platform with zero personal gain to them. Air Intake CEL Fix (P2C9000) – 555 Engineering Garage The 3.5” system will however, require a tune as the maf opening is much bigger then oem. Bigger piping, more air. A proper tune and calibration will be required for this oem + system but will be highly worth it if you’re going that route anyways. Please do your research regarding the CEL for increased intake size as well as aftermarket intakes. One fix may not work on all cars. How does it sound? Loud and unique as only titanium resonance can offer. It is very prominent inside the car and will sure to lower your mpg as you will have a hard time NOT hitting spool and boost!
