The problem is Toyota would have the same exact response if you took a defective filter back to them. There's no way they'd graciously accept responsibility to rebuild your 20+ year old 1FZ to the tune of $5-7k. The only thing you're getting by using OEM filters is the assumption (piece of mind?) that their quality control is to a higher standard than aftermarket filter producers. As @beno has alluded to several times on here lately, Toyota is on a bullet train to GM-ville with bean-counters running the show, not passionate auto enthusiasts. I'd bet before long we'll see this exact same thread but with the Thai-made OEM spec filter. Well, maybe better put...it wouldn't surprise me.
Give me one example to support your claim. Not speculation. An example of Toyota turning their back on a customer due to failure.
Look at what the two companies have to lose. Then realize the absurdity of your claim.
Wix loses your filter business. 3 filters per year for the next 40 years. Call it $600.
Toyota loses your business. They lose service business. Used car business (Mr T doesn’t care about this but the dealership does). New car business. Parts business. Over 40 years that is potentially tens of thousands of business. PLUS the negative word of mouth.
