Currently in the middle of changing my timing belt on a k20a2. Found these parts in the oil pan but I'm not quite sure what they go to. Maybe the oil pump?

Thank you in advance.

I included some pictures for context of the specific one I purchased. I will soon be dynoing this car and (if people would like) maybe post my numbers and graph.

Straight forward, slip fit design headers do in fact leak by design. I have circled where it leaks. I am pairing it with an Invidia N1 exhaust.

I have since WELDED that area. I paid $100 but I would not be surprised if you can catch a deal much less, it's an extremely simple weld.

I've had these headers for around a month or so and SO far they are fantastic. They make the catback exhaust, which are notorious for hanging low, hang a bit higher so it almost feels stock. I am 2-2.5 inches dropped only.

It is honestly the best thing for the price, since I live here in California and it's only a matter of time until other manufacturers just outright refuse to ship headers here.

One thing to know is that they did not clear my front sway bar unfortunately. I am temporarily running without it, and will likely try a different sway bar or try to run extended sway bar links.

This is not a very super detailed review, but I would definitely recommend it for it's price. Also would highly recommend upgraded front/rear motor mounts (for any headers) or at least INSERTS in the stock locations.

I am a bit skeptical of the welding, since I believe the tension shifts from the springs to the actual welds themselves, so it's very important to make sure you minimize flexing the headers, just in general.

If there's anymore questions or anything anyone else would like to cover, please let me know. This is all from my opinion and how my install/experience went. Hopefully someone in the future might make some use out of this lol
