Chevy Cruze 1.4L Intake Manifold Install Time: 3 hours
In the Box: • (1) Racer X Intake manifold• (6) M8x1.25 bolts• (4) M6x1 bolts• (2) 1/8” NPT plugs• (1) 3/8” NPT plug• (1) 1/4” NPT 90 degree barb• (4) Small O-rings• (1) Large O-ring• (1) PCV O-ring
Tools: • Socket driver• 10mm socket• 13mm socket• Pliers• Crescent wrench• Razor blade• NPT thread sealer• Flat head screwdriver• Allen keys
Instructions: 1. Start by removing the OEM air intake assembly and intake manifold. We suggest following the service
manual, although there are several online sites with removal instructions. We recommend removing the fuelrail from the vehicle. This means relieving fuel pressure from the rail. Please do so in a safe manner andagain follow the service manual for this procedure.
2. Optional PCV kit shown. Use pipe thread sealer on all fittings. Only 2 clamps are supplied with the kit. Theyshould be used where indicated. Be sure to check valve flow is in the correct orientation during installation.(Figure 1)
3. The fuel rail mounting brackets must be bent to accommodate the mounts on the intake manifold. We suggestusing a set of pliers and a crescent wrench. Slowly bend the tabs down toward the injectors. Check the railfitment, the tabs should be parallel to the mounting points on the manifold. (Figure 2)
4. Once the fuel rail is ready to be installed onto the manifold begin by lubricating the injector o-rings. Onceproperly lubricated, angle the rail at the bottom toward the injector ports. (Figure 3)
5. Slowly insert the injectors into the manifold, firmly press from the top of the fuel. The plastic guides below theo-rings may bind slightly, this is normal. Take your time and be sure not to tear an o-ring. A fully seatedinjector should look like this. (Figure 4)

6. Finally insert the small nylon spacers between the rail mountsand the manifold mount. Then thread in the M6x1 bolts to thebottom of the manifold and finger tighten. Once both are installed,use a 10mm socket to tighten bolts. (Figure 5)
7. Install manifold to cylinder head. It helps to remove the evap hoseand canister for additional clearance and room to work. Before bolting the manifold to the cylinder head,install the injector electrical connectors. Then using the supplied (6) M8x1.25 bolts, mount the manifold to thecylinder head. Remember to ground the rail to one of the bolts. Once in place, tighten bolts to 15ft/lbs.
8. Next install the OEM throttle body using the supplied M6x1 40mm bolts. Start all bolts before tightening, use a10mm socket and tighten throttle body. Install IC tube and tighten clamp. (Figure 6)
9. Install vacuum fittings, plugs and MAF sensor. We recommend using a thread sealing paste over tape. Thethread sizes on the manifold are as follows: (2) 1/8 NPT, (1) 1/4” NPT, (1) 3/8” NPT, (1) M6x1 for MAF sensor.(Figure 7)
10. The OEM thermoset line must be cut from the brake booster on the master cylinder. Using a razor blade,carefully score the line so it can be separated from the fitting. Once removed, run the supplied 3/8” ID linefrom the fitting to the supplied 90 degree 1/4” NPT barbed fitting. (Figure 8)
11. The brake booster line can be seen here. (Figure 9)12. Using the supplied 1/4” ID hose, run from the turbo BPV to the solenoid and manifold using the supplied 3/16”
vacuum tee. The small 5/32” hose should be used to connect to the solenoid. The red silicone caps should beplaced according to the picture. Be sure to use zip ties or clamps on the 1/4” line at the tee connection.(Figure 10-11)
13. The line routing can be seen in these additional pictures. (Figure 12-13)14. Run the 1/2” ID hose from the PCV tee to the turbo vacuum source. The OEM PCV line will have to be cut
from the OEM turbo fitting. Again, using a razor blade, score the thermoset line and remove. Using thesupplied 5/8” hose connect the OEM fitting using the 1/2” to 5/8” hose splice connect the two hoses. (Figure14-15)
15. Finally, install EVAP canister and line to manifold. The OEM fitting snaps into the top of the manifold. Thesmall plastic wiring harness located at the center of the manifold will need to be removed to allow for moremovement. Install all OEM electrical connectors, fuel system components and air intake assembly. Key onvehicle and check for fuel leaks, if there are no leaks start vehicle. Again double check for leaks.
