Wow! Unbelievable! These guys are GREAT!
Took my 2005 Toyota Sienna through emissions and it failed due the engine light being on. I knew the (2) knock sensors needed to. E replaced. After pricing the (2) knock sensors at Pep Boys ($171 per each sensor), Auto Zone ($165/each) and Advanced Auto ($166/each), I decided to go online and see what the prices were like. 1A-Auto, as usual, was my first site to check. Found the sensors and was blown away by the price!!! $50 for two!!! Ordered the parts and received them in 5 days. Sometimes it is convenient to go to the local auto parts place and pay a little bit extra to have right it then and there, but 1A Auto is my goto place to save money and get the parts quick, especially for my 05 Sienna. Kudos to the staff.
