fit and forget
This is a no brainer for the price. Whilst the cost is more than an OEM replacement it will be the one and only Air filter you will need and factor in the cost of replacing the OEM at every service it soon pays for itself. They come with a 1 million mile warranty, improves performance and fuel economy. Plus when it needs to be refreshed all you need to do is rinse the filter under water and reapply the oil to the filter.
