Product review (5 stars): Great alternative to factory filter for much less
I bought this as a cheaper alternative to the factory filter and am happy so far.  The installation was the same as the factory filter and was quick and easy.  The only thing I have yet to determine is the filter's longevity compared to the factory filter; so long as it's comparable, I'll maintain this is a 5-star product.

UPDATE: These filters last approximately the same length of time as the factory filter, making it well worth the purchase at the lower cost.
