Quick Snap: E63 BMW M6 Breathes Free with K&N Cold Air Intakes
It’s not often we get a E63 BMW M6 through the shop, so it’s something of an occasion when we do. Mod Expert Sean came up with some options to give the M6 a much more satisfying intake note under throttle and a bit more power.
Onto the lift, and out comes the stock intake.
This BMW M6 came in to be fitted with an upgraded Intake for E63 M6, developed by K&N. The dual airboxes of the V10 under the hood aren’t exactly ideal for flow, aimed more at limiting “excessive” noise. But dammit, we want to hear that glorious V10 sing - so the restrictive stock airboxes had to go.
Good for a rather impressive 21 horsepower gain, the K&N 69-2003 Intake for the E63 BMW M6 and E60 BMW M5 replaces those airboxes with a set of high flow conical filters and integrated heat shields.
The dual conical filters also give the engine bay a more performance oriented look.
Want to make your M6 look more your style? Need something installed?
