OXILAM Under-Seat Vent Deflectors for Chevrolet Silverado & GMC Sierra 2014–2019, Rear Pair 45° Upward Airflow

OXILAM under-seat vent deflectors redirect rear AC airflow up toward seated passengers in Chevrolet Silverado and GMC Sierra trucks from 2014–2019 for more comfortable rear-cabin cooling.

These plug-and-play directional deflectors replace the factory under-seat outlets to lift conditioned air away from the floor and toward occupants’ faces and torsos. Molded from durable PC plastic with internal fins, the pair includes two different lengths to match driver and passenger side duct runs and installs without tools by matching the original AC outlet connection.

How do these deflectors change rear passenger comfort?

The deflectors angle airflow upward 45° so cool or warm air reaches passengers more directly instead of dissipating along the floor. That delivers faster perceived temperature adjustment and reduces drafts at foot level.

• 45° upward outlet directs air toward seating height
• Internal fins stabilize and focus the airflow
• Two sizes ensure correct fit and even distribution

Will installation require tools or vehicle modifications?

Installation is designed to be tool-free: each deflector mates to the stock rear air outlet using the same connection geometry as the original vent. No cutting, gluing, or wiring is necessary, so you can install or remove them in minutes.

• Plug-and-play matching connection port
• Snaps into existing ductwork with no trimming
• Reversible removal for service or replacement

Are these durable and what materials are used?

OXILAM uses rigid polycarbonate (PC) plastic to resist deformation and retain shape over years of use. The internal ribbing and fin structure give the deflectors mechanical strength while keeping the airflow focused.

• Hard PC plastic resists warping and cracking
• Fins inside maintain directional flow and durability
• Expected long-term shape retention under normal cabin temperatures

Which trucks and parts are included in the package?

The kit is tailored for Chevrolet Silverado and GMC Sierra model years 2014 through 2019 and may fit similar GM platforms with the same under-seat vent layout.
