I have read and read and read some more, decided to get the IK22 plugs. When I try eBay, they say it doesnt fit my truck. Are all IK22s the same? I assume no, does someone have the 4 number part#? I know I cant find locally, just want to order them. 2001 4runner 4x4 limited supercharged (3.4). Is there a better place to order? eBay and Amazon would at least be no tax/shipping to me in Los Angeles. Thanks in advance for the help!

 

You're supposed to be using Denso or NGK plugs with two ground electrodes.

To answer your question, all you have to do is look up the NGK part number chart and verify that the IK22 plug has the same thread size, electrode style, heat range, etc as OEM.
