Guys, I live in the US. I need to purchase a replacement air filter for my 2006 HSE with the Jag engine. Which is the most decent one? Where I live, in Idaho, we have a very popular and well run chain of automotive part's stores called, "Napa". The have their own line of premium products, referred to as, "Napa Gold". These are just relabeled items from well known manufacturers. The Napa Gold version of a replacement air filter for my vehicle is $22. Anything wrong with the price or the brand? If so, what would you recommend, and if you happened to have a link it would be great too. Thanks for the help.
