    This is one of the oddest things I've seen. I just changed my spark plugs (30k miles on my 2007 Dble Cab TRD Sport 4x4 - 1GRFE V6) and when I did, I found Denso plugs in the pass. side of the engine, and NGK's in the driver's side. As my local toyota parts dept. only had the Denso's, that's what I put back in it on both sides. The manual lists an NGK and a Denso as the OEM approved plugs, but I never thought I'd find 3 of each in my engine. WTF?! Anyone else seen this? Of note, it's been running great for 30k miles. I've had no problems. But this strikes me as a bit odd to say the least.:confused:

    All Tacoma V6 engines are like this. Been like this for a few years. You got the right plug (Better in my opinion).

    The required resistance between the two banks is different. They can save a little money by useing less expensive plugs on one side without running into reliability issues. Though the saveings is only a few cents (or whatever), spread out over a 500,000 vehicle production span, the saveings is significant.
