If you’re ready to take your Speed 3 to the next level and have some big power potential, look no further than the CorkSport 4 Inch Intake. Sooner or later when shooting for very high power levels you will max out MAF sensor flow and need a larger intake to feed your engine all the air it wants. The CorkSport 4” Intake combines the ease of use of our smaller intakes with enough flow to support over 900whp. Read on for full details and more pictures.#ZoomZoom!
The CorkSport Advantage
Fitment Focused:
In order to make the CorkSport 4” Intake the best it could be, we went back to the drawing board to rethink the way we design our intake system. The main change is to the MAF housing connection; instead of a silicone coupler to attach the MAF housing, the billet MAF housing is TIG welded directly to the turbo inlet pipe. This gave us a ton of freedom to optimize fitment and filter size. You end up with a four inch intake that takes up less room than some 3.5” intakes while retaining all OEM mounting points and OEM BPV, PCV, and boost vent ports. It even fits with our 51R battery box!
Power Potential:
The main reason behind a 4” intake is the bonus power potential it offers. By moving up in intake size, you increase the maximum amount of air your car can ingest. With a tune, you also increase the amount of air the MAF sensor can read before it maxes out its voltage operating range. While typically not offering a power bump on lower horsepower cars, MS3’s already with big power can see an increase in power, just by reducing the airflow restriction before the turbo. This increases efficiency & increases the operating range of the MAF sensor to support over 900whp.
Optimized Filter:
The CorkSport 4” Intake System reduces flow restrictions by using a very large air filter measuring 7 inch in length and 4.5 inches at the MAF inlet. Filter size is something most large intake systems ignore, which can ruin some of the benefits of going to a large intake. After all, the pipe size does no good if the filter flows poorly and/or is too small. We chose aFe’s Pro Dry S material for fantastic filtration and flow without the risk of an oiled filter dirtying the MAF sensor. Check out the image, you can see how much bigger this is than our normal filters!
Accurate Flow:
While the design may be a bit different from our typical intakes, the CS 4” intake still retains a billet aluminum MAF sensor housing. When combined with the pre-installed air straighteners, you get stable and accurate airflow readings. This makes it easier to tune and ensures your car will consistently read the actual amount of airflow entering your engine.
Materials & Manufacturing:
Each CorkSport 4” Intake System is made from mandrel bent 4” 6061 aluminum tubing. This ensures good strength and smooth airflow into your turbo. The billet MAF housing and all ports are TIG welded in place for upmost strength and reliability. The main intake pipe is finished off in wrinkle black powdercoat for a clean look that will last and match any engine bay. Also included is your choice of turbo inlet coupler made from 4-ply reinforced silicone. We offer couplers to fit 4.0”, 3.5”, and OEM sized compressor housings. Finally, stainless steel T-bolt clamps are included to prevent vacuum leaks!
- A tune is required for installation of this intake. Your tuner must scale the MAF sensor to suit the larger diameter MAF housing.
- You will need to relocate and/or decrease the size of your battery and battery box to install this intake along with adjusting the wiring harness near the battery box and fuse panel. The CorkSport 51R Battery Box works great with the 4” Intake System.
- Certain intercooler piping setups may not work with the CorkSport 4” Intake.
