went to local parts store today to get a 14x3 K&N air filter. Saw an X-Stream assembly kit there but the price tag on the shelf said $59.99. and a coupon was posted for a free recharge kit with the purchase of a new filter. well took the X-Stream kit to the counter and when he scaned it the price was $135. told the guy what the tag said and he went and looked. well it was actually for a different X-stream kit but didn't know why such a price difference. anywho, he offered me it for $75, hell yea i took it. $150 worth of stuff for $75.
