My suggestion on the reproduction ram air would be "NO".
That cheap fiberglass is all crap in my opinion.
It looks cheesy and the air cleaner is to me sorta like the steering wheel is.
Its the "piece de resistance" the cream de la creame".
Basically in redneck terms its one of those pieces that is the first thing you look at when the hood is raised.
When you get in the car the first thing you look at is the steering wheel in your hand right?
To me there is nothing worse that opening up a hood and seeing a ram air hood not connected up to a ram air air cleaner properly with the correct gaskets and equipment.
Its like the rest of the car just failed inspection when I see that.
Think of it like this.
Have you ever looked at craigslist ads on great Mach 1 mustangs then scan through the photos then see that the whole car looks great, the customer wants mad money and then you see that he has a cheep Chineese aftermarket steering wheel on it or that the Air cleaner is a $20.00 cheapy?
Just saying.....................
Fiberglass is also prone to burning if the situation is just right. A good real OEM air cleaner pan is metal and wont catch fire. The costs are expensive though.
Your car is yours. Make it your own.
