So far so good. Have seen an increase in horsepower and sounds great. Did not install myself had mechanic do it. Would recommend to everyone.

Use one on my F350 diesel (factory) and bought aftermarket CAI for use on my F250 gas motor. Replaced filter with one of these and noticed .3 mpg improvement and easier engine "breathing". Believe it will easily pay for itself.
