It took me about 35 minutes to install on my 87 Toyota supra. When I first ordered this I thought it came with the tubing for the intake as well. It actually just comes with the filter and the custom fit adapter to replace your stock filter. I can definitely tell the difference at the higher RPM's now with better throttle response and acceleration. It makes a pretty cool sound too when you punch it, kinda like a turbo sound the K & N filter gives off. Overall I would recommend this product to anyone. It's worth the money!
