I received this filter promptly. It's easy to install....instructions are clear and easy to follow....just don't try to jump ahead. I had some slight difficulty with the Toyota filter cover....could not slip the new filter past the cover. I had to remove the cover. While I had it off, I cleaned it thoroughly and re-installed it over the new K&N air filter. Everything fits well. Suggestions: supply a sticker to be installed over the outside cover with the message DO NOT REMOVE OR SERVICE FILTER. OWNER WILL SERVICE.
