inside air filter

[defcon1]

what size is this filter, i only have 3,000 miles on my car and no problem with it but for future info i'd like to replace it with a house filter if i could

simply take out your current one, use it as a template, and cut out a new one from a 20x20x1 sheet. Lowe's sells high performance Dirt Demon filters (3 to a pack) for under $10. Don't waste your money on using a OEM filter since these things need to be replaced VERY often

thanks for the help
