Cold Air Intake Kit for 2012-2019 Toyota Tundra 4.6L V8 Gas

🏁 Your Tundra's V8. Finally Breathing.

The 2012-2019 Tundra 4.6L is a proven workhorse. It tows, hauls, and goes where you need it. But that factory air intake system — a molded plastic box with a tiny paper filter — was designed for one thing: keeping costs down.

It flows like a garden hose.

Flashark's cold air intake converts your Tundra from choking to breathing:

→ 101mm smooth-bore aluminum tubing (massive flow capacity for a V8)
→ Oversized dry cotton filter with nearly 2x the surface area of stock
→ Intake temps 20-30°F cooler vs. stock airbox under load
→ Noticeably stronger mid-range pull
→ No tune required — factory ECU adapts
→ Direct bolt-on — no cutting or drilling

Tow harder. Haul more. Sounds better.

🔧 Why Flashark? 5 Reasons

1️⃣  101mm TUBING — BUILT FOR A V8

The 4.6L Tundra V8 breathes big air. The factory intake was sized for emissions, not performance — it chokes your engine at peak load.

Flashark's 101mm mandrel-bent aluminum tubing is the right tool for the job:

• Largest diameter available for this engine platform
• No flow-restricting bends
• Smoother transitions at every junction
• MAF signal stays clean — no CEL

→ More air = more power, especially under towing loads

2️⃣  DRY FILTER — BUILT FOR WORK TRUCKS

The Tundra isn't a garage queen. It goes to job sites, trails, and dusty highways.

Flashark's dry cotton media filter:
• No oil to collect dirt and dust
• Wash and reuse — no re-oiling
• 6.5" XL cone = massive surface area
• Maintains airflow even when dirty
• Lasts the life of your truck

Truck guys don't want to mess with oiled filters. We get it.

3️⃣  HEAT SHIELD — COLD AIR, NOT GRILLE AIR

The engine bay of a full-size truck runs hot — especially when towing on a hot day.

Flashark's heat shield enclosure:
• Seals the filter from engine bay heat
• Draws cold air from the grille opening
• Maintains cooler intake temps even under sustained heavy load
• Full enclosure keeps out road debris

The filter stays cool when you're working the truck the hardest.

4️⃣  NO TUNE. NO PROBLEMS.

The 1UR-FE is a proven, reliable engine. Flashark's MAF housing is precision- machined to match your factory ECU's expected airflow profile.

→ No check engine light
→ No trip to the tuner
→ No warranty concerns
→ Just bolt it on and drive
