We took a virtually brand new 2025 BMW M340i Touring (8k miles, still under warranty) and cranked it to ~420HP with a full AC Schnitzer upgrade! 😱

Watch the complete install:

👉 AC Schnitzer tuning module (plug-and-play +15% power / +20% torque boost)
👉 Full AC Schnitzer rear slip-on exhaust (stainless with carbon fibre tips, dual valves for real control)
👉 dAHler valve controller kit (remote override for open/closed modes anytime)
👉 JQ Werks magnetic shifter paddles (audible & tactile "click" feedback on shifts)

Deeper, throatier sound (like a pre-GPF M340i), way more mid-range punch, and still fully warranty-friendly. This is the mod combo every M340i owner needs!

If you're chasing more power without voiding warranty or spending big, hit play now.
