How To Install EUROCOMPULSION V4 Intake
I had an opportunity to try out the EUROCOMPULSION V4 intake, so I decided to write a brief tutorial for the install.
The factory ribbed intake tube on our cars is a bit restrictive and does not insulate against engine bay heat very well. EUROCOMPULSION has a V4 intake that solves both of those problems, reducing intake temps by over 12 degrees F on average, and increasing power by a peak of over 12 HP. The filter on this intake has a large filtration surface area, which allows it to produce more power than stock or V1/V2 intakes.
- 10mm socket, ratchet, and extension
- Flathead screwdriver
- Phillips screwdriver or 9/32" & 3/8" hex socket bit
- Optional: Ft-lb torque wrench
- Optional: soapy water

1. To begin, remove the engine cover.
2. There are 7 points we will be disconnecting in this tutorial, marked below.
3. Begin by loosening the hose clamps at the two ends of the intake tube using either the Phillips screwdriver or 9/13"/7mm hex socket bit.
4. Using the pliers to open the hose clamp, remove the 90 degree elbow going into the top of the intake tube.
5. Using the 10mm socket, remove the bolt securing the PCV tube.
6. Using the pliers to open the hose clamp, remove the rubber hose from the PCV tube.
7. Disconnect the coolant hose running across the top of the intake by wedging a flathead screwdriver underneath the toothed fastener.
8. Once you have everything disconnected, pull the intake tube off of the turbo and air filter box, and pull the PCV tube out of the intake (this may take some twisting of the intake.
9. Move over to the passenger side of the air box and, using a flathead screwdriver, pry the retaining clips away from the hose. These need to be clear on both sides of the clips, as shown in the second image.
10. Once the retainers are opened, simply slide the hoses off. Snap the air box clamps open, remove the bolt holding the air box to the front header, lift the top off the airbox, and remove the air filter.
11. The airbox bottom is now ready to be removed from the car. Lift upward gradually from the driver side, and the air box should pop out of the grommet and will be free to remove from the engine bay.
12. Install the EVAP hose provided with the kit in the bottom of the intake. The other two ends are connected to the OEM hoses that were disconnected from the factory filter box.
13. I found it easier to install this intake by removing the bolt securing the factory ram air outlet.
14. Install the elbow with the short side in the factory ram air outlet. I found it easier to use some soapy water on the inside of the hose to get it to slide over.
15. Slide the hose clamps over in the orientation shown below. I chose this orientation to prevent any rubbing against wiring or other hoses.
16. Connect the shown hoses to the upper section of the intake, and set it aside. Do not slide it over the turbo yet. I let it hang off the battery tray bolt so it stays out of the way.
17. Install the filter into the bottom section of the intake, then fit the top section in the filter and over the turbo. Note: the air filter has to be installed such that the opening of the filter cone (look inside) is facing the factory ram air outlet.
18. Ensure that the EVAP hose is underneath the air filter to prevent any rubbing.
19. Tighten all clamps securely (but not excessively), and re-attach the two bolts removed (one secures the factory ram air outlet, not pictured below) to approximately 12 ft-lb.
20. Included in the kit is a hose with a slit going through it. Fit this hose over edge of the battery sleeve to keep it from rubbing against the intake hose.
21. Reinstall the engine cover, and you're done!
