N55 BMS Intake Heat Shield

Wanted to share the intake cover/heat shield I made for the BMS N55 intake. Inspiration came from user TVD75. I started with the information he supplied and adapted from there. Material is 14 Ga stainless steel with a lexan cover. I added some tabs on the outside to tap back into the original screw locations. Only problem is that it is tight against the hood sound dampening, you can see the indentations on the liner.

The only benefit I see with this is showcasing your engine bay during car meets.

The OEM setup includes an intake box that is sealed and pipes cold air in via a pipe that draws in air from the front of the car, which you can see forward of the intake. The BMS intake does not allow you to re-install the OEM intake cover because of the increased size of the filter. A typical BMS intake install will not have any type of heat shield (BMS does not make any type of cover), sucking in hot air from the engine bay. The purpose of this box is to create a barrier against the hot air in the engine bay and the intake, forcing the intake to suck air back through the OEM pipe. Of course this box does not create a perfect seal so some hot air will still seep in. The secondary purpose of the box is visual, hence the use of lexan rather an opaque material. Hope that clarifies what I was trying to achieve.

Looks cool but the flow restriction is the smaller original airbox opening, which is why the intake is designed without a lid in the first place.

good effort, but wonder why would there be a cabinet/organized box in the engine bay

I get what you were trying to accomplish and just wonder what the HP gain by shielding any heat from the engine bay. As far as the finish it looks great and all that matters if you are happy with the finish product. Thanks for sharing!

I don't expect any HP gains, not really getting any from the filter by itself anyway. The purpose is to try to keep cool air going to the car and to make the intake setup look good.

Can you provide guidance on this? If you made one of these for sale I would totally purchase it.

Do you have access to a 2D program such as Autocad? I could give you the flat pattern of the parts. If not, I could provide a drawing detailing dimensions. I don't have any plans to sell right now, sorry.

I doubt this will perform better then stock unless you are modified.

Looks very nice but also looks useless since the OEM air duct is the biggest restriction point and not the actual filter. Otherwise just throwing a K&N drop-in would do the trick without all the trouble you went into.

Still congradulation for you DIY skills and being different.
