Using a “clean sheet” approach may not be the quickest way to solve a problem, but it often results in a better solution. That’s the philosophy used by the folks at Holley Performance Products when designing their new iNTECH line of cold air intakes. One look at the arrangement of their intake and it’s clear the iNTECH design for the 2015-2017 5.0L Mustang is unlike anything on the market.

For starters, the high-flow, washable and reusable conical filter is pointed down inside a fully sealed filter housing to ensure the engine is fed the coolest, densest air possible. This unique design maximizes the air inlet tube length and laminar flow across the mass-air sensor, which is critical to performance and drivability. Not only is the filter location unique, but also the patent-pending “Slip-Seal” fit eliminates the need for separate hose clamps to seal the filter to the system.

The Holley iNTECH cold air intake system uses a silicone bellows coupler at the throttle body to accommodate engine movement and accessories such as nitrous plates without modification, and the air box mounts to the factory locations to make installation a breeze.

Just because installation is easy doesn’t mean the power gains are small. In fact, the Holley iNTECH cold air intake system added over 23 peak horsepower and 28 pound-feet of torque at the rear wheels, but the torque gains were fat from idle to redline. Impressive. Let’s take a look at what it takes to install one of these systems on a 2017 Mustang GT.

1. Holley’s iNTECH cold air intake system for 2015-2017 5.0L Ford Mustangs features a reusable, washable filter, durable intake tube and filter housing, and all necessary hardware and clamps. The iNTECH air filter housing draws cold air from the same location as the OEM housing.

2. All Holley’s iNTECH cold air intake systems use patent-pending “Slip-Seal” technology to seal and retain the filter in the housing and inlet tube in the filter without any clamps. Slick!

3. Holley’s Ethan Townsend helped us with the installation process that began with removing the OEM engine cover.

4. Next, we disconnected hose fittings from the OEM intake tube.

5. We used a pair of pliers to loosen the sound tube’s spring clamp and pulled the hose from the intake tube.

6. We then disconnected the mass-air flow sensor connector.

7. Using a socket, we loosened the clamps holding the intake tube to the throttle body and air filter housing.

8. With the clamps loose, we removed the OEM intake tube.

9. We used a socket to remove the bolt retaining the OEM air filter housing from the inner fender.

10. After carefully prying up on the air filter housing’s rubber isolators, we removed the OEM air filter hosing from the car.

11. With the OEM air filter hosing removed, we relocated the wiring harness so the MAF sensor connector can reach its new location on the Holley iNTECH intake tube.

12. With the OEM air filter housing removed, we compared the small flat panel filter with the conical Holley iNTECH air filter. Some of the additional power offered by the iNTECH cold air intake may be credited to the lower-restriction, conical filter.

13. We dropped the filter into the voluminous iNTECH air filter housing.

14. We transferred the OEM air filter housing grommet from the OEM housing to the iNTECH filter housing.

15. With the filter and grommet in place, we installed the iNTECH air filter housing into the Mustang’s engine bay.

16. We then used a socket to install the OEM air filter housing bolt.

17. Next, we transferred the MAF meter from the OEM intake tube to the iNTECH intake tube using the supplied screws.

18. We then installed the supplied hose fittings in their respective locations.

19. Our 2017 Mustang GT didn’t use the third hose fitting, so we used the supplied NPT plug to cap off the unused hole.

20. We placed a clamp over the supplied silicone coupler, and installed the coupler over the throttle body.

21. With the coupler in place, we installed the air intake tube.

22. With the air intake tube in place, we tightened the clamps on the throttle body coupler.

23. We then installed the hoses onto the iNTECH air intake tube.

24. We reinstalled the MAF meter connector.

25. The Holley iNTECH cold air intake system complements the engine compartment of this 2017 Mustang.

26. The Holley iNTECH cold air intake system added over 23 peak horsepower and 28 pound-feet of torque at the rear wheels, but the torque gains were fat from idle to redline.
