i just finished making and installing a dual snorkel aircleaner on my 83 bird. It cost 15 for two aircleaners and took about one and a half hours and let me say it was well worth it. I took it for a drive and noticed better throttle response, slightly improved acceleration and a meaner, deeper tone from the engine at WOT. Anyone with a crappy one snorkel cleaner shou;d do this, instructions are in tech articles.

For 15 bucks and under two hours of my time, it was more than worth it!

 

Cool, I am going to get one asap! How much should you pay for an air cleaner?
