DC Sports Cold Air Intake Specifically Designed for 04 – 08 Acura TSX

DC Sports Cold Air Intake for 04-08 Acura TSX

Unlock hidden power, crisper throttle, and a rich induction growl with the DC Sports Cold Air Intake for 04-08 Acura TSX. By replacing the restrictive factory rubber tube with a single-piece, mandrel-bent aluminum runner, this system feeds your K24A2 a steadier stream of dense, cool outside air. The result? Measurable gains in horsepower and torque across the rev range, faster mid-range response, and that unmistakable deep intake note every TSX owner craves.

Key Performance Highlights

• True cold-air design – relocates the filter into the fender well where temps stay up to 30 °F cooler than under-hood air, maximizing oxygen density for stronger combustion.
• High-flow, reusable DC Sports oiled filter – pleated cotton media delivers superior filtration while out-flowing paper elements; just wash, re-oil, and reuse.
• Lightweight 6061 aluminum construction – smooth 2.5″ ID tubing eliminates turbulence, resists heat-soak, and wears a durable wrinkle-black powder coat that complements factory engine bays.
• 50-State C.A.R.B. compliant (EO# D-370-15) for 2004-2007 TSX models, so you stay legal at the smog station without sacrificing performance.*
• Direct bolt-on fit – engineered specifically for the CL9 chassis; precision-molded silicone couplers, stainless T-bolt clamps, and all brackets are included.

Daily-Driver Friendly

No check-engine lights, no hunting for oddball sensors—just install, turn the key, and enjoy smoother part-throttle drivability with a sporty soundtrack that stays civil on the highway.

Built by Enthusiasts, Proven by Testing

Dyno sessions show consistent gains of 5–7 whp and 6–9 lb-ft of torque on stock ECU calibrations. Back-to-back heat-soak tests confirm faster IAT recovery versus OEM piping, giving you performance you can feel lap after lap or on the morning commute.

*2008 TSX owners should verify local regulations, as CARB coverage applies to 2004-2007 model years.
