The 2015–2017 S550 Mustang's 3.7L Cyclone V6 makes a healthy 300 hp from the factory — but you'd never know it from the intake note. Ford buried the induction path under a labyrinth of plastic resonators and Helmholtz chambers designed to make the V6 sound like… nothing. The result is an engine that breathes through a muffled straw, suppressing both airflow and the V6's natural induction growl.

This Flashark cold air intake replaces that restrictive factory plumbing with a black powder-coated aluminum intake tube and a high-flow dry cone filter, paired with a metal heat shield that retains the factory lower cold air box. Cold outside air still feeds from the fender well inlet — the difference is how fast it reaches the throttle body, and how good it sounds on the way.

Expect 5-12 WHP and noticeably sharper part-throttle response, but let's be honest about what you're really buying: the moment the throttle opens past 3,500 RPM, that 3.7L finally sounds like a Mustang. No ECU tune, no permanent modifications — a 45-to-75-minute bolt-on that transforms the driving experience.

Key Features

Black powder-coated aluminum intake tube — mandrel-bent for smooth airflow, corrosion-resistant finish designed to last

High-flow dry cone filter — no oil required, cleanable and reusable every 15,000-20,000 miles under normal driving conditions

Metal heat shield — separates the filter from direct engine-bay heat while preserving the factory lower cold air intake box

Retains factory lower cold air box — continues drawing outside air from the fender well inlet, not hot engine-bay air

5-12 WHP gain — honest real-world range on an otherwise stock 3.7L Cyclone V6 (dyno results vary by conditions, fuel, and supporting mods)

Sharper throttle response — reduced intake restriction means the engine reacts faster when you tip into the pedal

Deeper induction growl — the Cyclone V6 finally sounds like a Mustang above 3,500 RPM; calm at cruise, aggressive under throttle

No ECU tune required — plug-and-play with the factory MAF sensor in the correct position; a custom tune is optional for cars with headers, throttle body, or other supporting mods

Bolt-on install — 45-75 minutes with basic hand tools; no cutting, drilling, or permanent modification
