I was able to get 3 filters (i was down to 2 and just changed oil on both cars) from my dealer here in San Diego. I use them on my GT350R as well since it makes 1100 RWHP. If anyone needs one locally let me know. Just pay me the dealer price.
I have one... all you need is the boot since i reused it when i did my TR6060 swap... send me your email and i can send you pics. I used it for about 10k miles
