Would give 5 stars if it wasn't for the unexpected shipping charges to Canada... I placed my order online at the dedicated Cdn site (knfilters.ca) on a weekend, and was pleasantly surprised when FedEx attempted to deliver my air filter Monday afternoon. Incredibly quick delivery, by air mail it turns out. I installed my new air filter and I'm happy with the results so far, while no perceived power increase, my fuel economy is noticeably better. However, two weeks after receiving my order, a letter came in the mail from FedEx, containing a bill for CAD $18 which FedEx was asking me to pay to cover GST + PST + their $10 handling fee. This was unexpected, as I had picked up my order at the nearby FedEx facility here in metro Vancouver, and they did not indicate any further charges were due at that time (and I asked). Kind of left a bad taste in my mouth, since the money I'd saved (CAD ~$20) by ordering direct from K&N, compared to buying the same filter at my local NAPA store, was basically cancelled out. Also it would be better if the dedicated Cdn site (knfilters.ca) listed its products in CAD rather than USD, so we Cdn customers don't get hit with the savage exchange rate fees by our (Cdn) credit card company
