Finaly put together a cold air system for my 1970 Nova SS, 350, 4spd. Installation was really easy and the performance change was obvious, immediate and appreciated. This is definitely a must do for the added horsepower, looks and hopefully gas mileage. Thanks Spectre for your assistance in the parts selection and really fast shipping.

Do you know how hard it is to get a part like this one. And it fit perfectly. It came in a black box in a almost velvet black bag. It shows off the quality of the complete product line, from packaging to installation. I thought this was going to be silver plated. Awesome part for under the hood. I have a blue car with blue valve covers and used the silver duct with the blue couplers and aluminum flanges. I did not expect a horse power increase and was not looking for one, but I bet I got 20 HP more out of the total setup. I must have been choking the motor with the old air filter.
