I put a fiberglass hood with 6 pak style scoop on my charger, sealed it to the carb with an air cleaner. dropped nearly 4 tenths of et and picked up 3.5 mph in the quarter. I then added a wide band o2 in the exhaust, further tuning dropped .08 of et and another .5 mph. Definitly worth money and effort.
Almost forgot to mention that with the hood scoop I was able to add a 1 inch plastic spacer under the carb. I didn't test them seperatly so I don't know what the improvement is seperatly.
