For 2012-2015 Toyota Tundra V8 5.7L High-flow Cold Air Intake Kit

The Toyota Tundra's 5.7L V8 (3UR-FE) is already a powerhouse — but the factory intake system treats it like a commuter sedan. Toyota packed the 5.7L with a bulky airbox and undersized plastic tubing that chokes airflow and starves the V8 of the cold, dense air it needs to make real power.

The Flashark High-Flow Cold Air Intake Kit changes that. Built around a large-bore 4" (102mm) mandrel-bent aluminum intake pipe and a high-flow cone filter, this kit significantly increases the volume and density of air reaching your 5.7L — unlocking sharper throttle response, stronger low-end and mid-range torque, and a deep V8 induction growl the factory system completely kills. An integrated steel heat shield keeps engine radiant heat away from the filter, maintaining cold air temperatures even during hard pulls or towing.

True bolt-on fitment for 2012-2015 Tundra V8 5.7L. No cutting, no welding, no fabrication.

Features:

4" (102mm) Large-Bore Aluminum Intake Pipe — significantly larger than the factory plastic tubing; paired with two Φ29 vacuum nipples for direct connection to factory breather lines without adapters

High-Flow Red Cone Air Filter — washable and reusable dry cotton gauze filter (152mm inlet / 190mm net height / 130mm top cap / 180mm base); no oil required, far better flow than OEM paper elements, lasts the life of the truck

Full Steel Heat Shield Included — large-format steel heat shield mounts to factory locations, creating a sealed cold air box around the filter; critical for maintaining intake temp gains on a high-heat V8 engine bay like the Tundra's 5.7L

Nylon Filter Base (Φ82) — CNC nylon base adapter ensures a sealed, rattle-free connection between the filter assembly and the intake pipe; no vibration, no air leaks

Dual Reducing Silicone Couplers (Φ89-101mm) × 2 — multi-ply high-temp silicone reducers handle the transition between factory rubber hoses and the 102mm aluminum pipe without restriction

Breather Reinforcement Hose (Φ13mm × 185mm) — connects factory crankcase breather port directly to intake system; eliminates vacuum leaks and CEL from breather line disconnects

3× Steel Mounting Brackets — dedicated mounting hardware engineered for factory Tundra mounting points; no flex, no vibration under V8 load

Vibration Dampening Strip (1910mm) — full-length anti-vibration foam strip wraps the intake pipe to prevent rattle and protect the aluminum finish in the Tundra's high-vibration V8 engine bay

Powder-Coated Black Finish — durable matte-black aluminum pipe resists heat and corrosion; looks purpose-built in the Tundra 5.7L engine bay

Complete Hardware Package — all stainless steel clamps, aluminum spacers, bolts, and washers included; nothing extra to buy

Why Upgrade Your Intake?

The 5.7L 3UR-FE V8 in the Tundra is one of Toyota's best engines — proven, reliable, and genuinely powerful. But the factory intake system was engineered around noise suppression and cost targets, not performance. The result is an airbox that restricts the V8's breathing at exactly the RPMs where you need power most: towing, highway merges, and anything above 4,000 RPM.

The Flashark Cold Air Intake fixes the bottleneck:

• More usable torque for towing — the 5.7L Tundra is a work truck first; a free-flowing intake gives you the low-end and mid-range grunt you need under load
• Sharper throttle response — the V8 answers immediately under acceleration; no hesitation, no bog
• Real V8 induction sound — the factory airbox was specifically designed to suppress intake noise; the Flashark intake finally lets the 3UR-FE sound like what it is
• Heat shield keeps temperatures down — critical on a truck engine that runs hot; the full steel heat shield blocks engine radiant heat to maintain cold air density
• Reusable filter for life — no more $40+ OEM paper elements every 15,000 miles
