NGK # 4996 - Laser Iridium Spark Plugs - IFR5T11-4 PCS * NEW *

$36.00...What a deal! Paid $76.00 at Auto Zone for the exact same plugs before purchasing these. I returned the other plugs and saved $30. I thought the package and the plugs from this seller were identical. If these aren't authentic I couldn't tell. I've put about three thousand miles on my 09 Prius since installing them and milage has improved and the car runs great. I guess time will tell but so far so good.

Best in its use. Just plug and play. No need to gap, or paste for vibration

Installed these in a vechicle and it's working well. No issues at all.

Pulled out factory old one's and these were the same plugs they use on my 2012 scion xb, no problems as of today. Highly recommend

These spark plugs replaced identical plugs installed 100,000 miles ago. I was very satisfied with the performance of the NGK plugs over the past 8 years or so. I expect these plugs will perform just as well for the next 100,000 miles. If the vehicle is still chooching along, I'll grab another 4 pack of these!
