Added the VelossaTech BM snorkel set with LEDs to my DH today:

I also replaced the old crappy phillips D1S with Osram NightbreakerLasers, it's a world of difference!

Why? The 3.8 has a pretty clean shot to the front already. You'll get more low-end performance improvement if you remove the flapper in the airbox, under the filter. Also - that engine only has an intake on the passenger side. You're just obstructing airflow to the rad by putting another on the driver's side.

I cut out a rectange just behind the first bend on the drivers side funnel to get air to the radiator, and I reinstalled the shroud after cutting some parts of it (to also get the air to the rad), I mainly did it for aux lighting.
