I've found the Nissan places are cheaper for the same thing, pintle caps and injector o-rings, than subie places and typically get mine from a local Z place for about 2 bucks each, which is usually cheaper than online stores when shipping needs to be paid for. As for missing caps, I have pulled injectors from motors with as many as 3 different caps per set, sometimes some with no caps and even when servicing super low mileage, like 12k miles, cars at the dealership, that are mismatch. I doubt that a minivan with 12k on it had any aftermarket injectors installed, mostly because it is a minivan. lol
I honestly don't think most, if any, actually require the pintle caps to operate properly, but I may be wrong. BUT if OT says that they serve a specific function, I would heed his word.
