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. We're upfront about this — please be sure of your purchase before ordering.

K&N 57-0078 for BMW 318i 1.8 E30 and E36

Give your classic 3 Series the crisp throttle pick up and richer induction soundtrack it deserves. The K&N 57-0078 intake kit replaces the restrictive factory airbox on BMW 318i 1.8 petrol models, opening up airflow for a more responsive drive and a purposeful engine note. Built around K&N’s famous oiled cotton gauze cone element, this upgrade is engineered for everyday use and weekend blasts alike.

We run this kit on our own cars at MJ Modifications and customers love the clean fit, quality hardware and the way the car breathes. It is a straightforward bolt-on that delivers instant grin factor.

Why enthusiasts choose this kit

  • Free-flow inlet path that helps the engine breathe more easily for sharper pedal response.
  • Washable and reusable filter element to reduce long-term maintenance costs.
  • Direct-fit assembly tailored to 1.8-litre 318i applications across E30 and early E36.
  • Durable components and brackets designed for a neat install in the engine bay.
  • Enhanced induction tone that complements classic BMW character without being intrusive.
