Heads-up on cancellations & returns: if you cancel an order or return an item, you won't get back 100% of what you paid. We apply a 10% restocking fee, the outbound shipping is non-refundable, and we have to pass on Shopify / PayPal payment processing fees; these aren't returned to us when we refund you. International orders also lose on exchange-rate spread in both directions. If the original packaging is damaged or missing, a reboxing charge applies. For international orders specifically, if you refuse to pay our shipping invoice or supply a prepaid label after placing the order, the same deductions apply.

K&N 57-1003 Intake Kit for BMW E46 M3 S54 3.2

Unlock the S54’s character with the K&N 57-1003 induction upgrade. This premium open-filter conversion replaces the restrictive factory airbox on the E46 M3, giving your straight-six a freer-breathing setup, crisp throttle pick-up and that addictive motorsport-style intake note enthusiasts love.

At MJ Modifications we have installed this kit on our own cars and for many E46 M3 owners. Feedback has been consistently excellent, with drivers praising the sharper response through the rev range and the richer, more engaging induction sound without compromising day-to-day drivability.

Why choose the 57-1003 for your E46 M3?

  • Direct-fit conversion tailored for the BMW M3 E46 with the 3.2 straight-six S54 engine
  • Free-flow design to reduce intake restriction and let the engine breathe
  • Noticeably enhanced induction tone for a more engaging driving experience
  • Simple bolt-on installation with no cutting of bodywork required
  • Reusable K&N filter element for long-term serviceability
  • Trusted by enthusiasts for fast-road and track-day builds

If you want a straightforward, proven intake solution for your S54B32, the K&N 57-1003 is a top pick for sound, response and quality.
