Ventilation through the front license plate area is actually a worthy modification, increases low density, higher pressure air along the intake filter area. Save that $500 bucks for porting.

Scott, any chance you still have this? Was it the 84-90 kit, or the 91-96 kit? I have been trying to find an unmangled set of instructions and the cutting templates. I'd be happy to pay shipping to myself in Massachusetts, copy them, and send them right back undamaged. Thank you. |

I had the A/O ram air intake system. It look nice ,but is not very efficent at
getting cold air into the car. I made my own cold air system using the A/O opening in the front bumper to the stock air filter housing with a cover to seal the filter from engine heat. The effect was that only outside air came into the sealed air filter housing and not engine heat.

I just want the license plate piece for the 84-90. I don't need the rest. If I knew osomeone with one I would have it 3D scanned

Hey John, I don?t know all the science behind designing the perfect cold air or forced air inlet, but I really don?t like the stock design knowing how hot the temps are in the engine compartment. The stock system is just very poorly designed. For shits, grins, and giggles I?m modifying the Breathless vortex system with similar thoughts like you to insulate the intake from heat and draw cool air in through the housing where it comes in from the bottom. It surely can?t hurt. Sent from my iPhone using ZR-1 Net Registry

Let me know when you get it. I might just need to good pictures and measurements. I don't own a 3D and will need to find where to get it done, but I could probably model it
