awesome product
it is really amazing quality and workmanship!
It worked first time out of the box with just a little adjustment. We had to do a slight trimming of forward edge where it goes into the intake due to running non-standard honda cylinder (Athena cylinder is different), but other than that it was perfect! Could not be happier!!! Great power and performance over stocker.
