With inspiration taken from the BMW E46 M3 GTR street/road car  N15's unique designs offer a high quality, beautifully engineered, fully functioning, and lets face it, pretty awesome looking vent system for your E46 or E36 hood/bonnet (see other listing for E46 and E36 Side Vents). 

The vents are both an aero and cooling device offering a noticeable improvement in both categories. They are perfect for both track or road car enthusiasts. They come flat in raw aluminium offering you full control over the end result. 

The vents are constructed from aircraft grade aluminium and will not corrode easily. They are very easy to prep for paint, just lightly sand, primer, and paint. Other options include PlastiDip or overlay of vinyl sheet before cutting between the slats and bending.  

The vents are designed to avoid any cutting of the inner hood structure. The thicknesses of the material is such that the bent tabs can be bent to shape but are not easily bent back once set. A full set of instructions, cutting templates, and aluminium rivets are supplied with each set
