Avoid cheap aftermarket, they crack asap so they are expensive.
DSS, Cmsnl and where they sell Honda original parts.

Cheapest OEM is likely jtmarks@hvc.rr.com (sells on eBay and is member here). Send him an email with parts numbers and he'll send you a PayPal invoice. Very fair shipping too.

  If the old ones are not cracked but hard and stiff a heat gun will soften them up long enough to work with them. New is good also if the quality is there.  Old hard and deformed air box boots are a pain in the arse also !
