K&N Replacement Air Filter
  • Designed to Increase Power
  • Million Mile Limited Warranty
Alan Parkes, Holland, Michigan
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.

These air filters are an excellent product and if cleaned and re-oiled twice a year or more often as needed, they will indeed last forever.
