I had the same problem with my R2C intakes. The company supplied really flimsy hump couplers. Solved that with some really nice and sturdy hump couplerd from Z1 Motorsports. They are longer and far more studier than the couplers supplied with some kits.

No worries I'm sure you are fine... 300mi isn't really that much to have a small air leak.

excessive dust from intake leaks can show up in an UOA from what I've read from various sources, one of which is:

High Silicon in Engine Oil Analysis

"Particles of airborne sand and dust vary in size, shape and abrasive properties. In an engine the ingress of atmospheric dust takes place primarily through the air intake. Efficient air filters remove 99% of the dust that an engine ingests. The remaining 1 % consists of very small dust particles that pass through the air filter. These vary between submicron size particles to particles up to well over 10 microns in size. This dust will pass between piston, rings and cylinder and eventually become suspended in the lubricating oil."

I imagine it's possible but not with just 300 miles unless there were a lot of abrasives like a sandstorm type condition. Remember it wasn't that large an air leak. I think they are suggesting long term abuse.

I just got Check Engine Light too...s***...lol I think I got it because of the HFC. I prob have to reset ECU soon

to the guy with "major scoring" complaints dirtbikes and atv's have been raced with no filters for a long time and while it does kill the motor eventually (unless it blows from the power) they go through a HELL of a lot more dust than he did. if he's really worried about it he could have it compression tested and have them check the cylinders with a bore scope when they pull the plugs. I say don't worry about it put it back together, reset the ecu, and if god hates u and u have to bring it in DON'T mention it to the service advisor.

Yep I get them every 3-400 miles now. Just do the manual reset with the gas pedal.

The OP is going to commit suicide.....

Here's a couple of pics of the hump couplers from Z1 Motorsports. First the left
Now the right.
Don't think that these will slip off anytime soon!
