Hopefully someone on here can help me figure out a strange noise. Just in the last day or 2, I have noticed a weird sputtering noise that sounds like it is coming from my intake (K&N SRI). It only happpens at high RPMs, well in to VTEC (like 6900 - 7000 range) and continues until I shift. I notice it in all gears, but it doesn't really seem to be affecting performance. Any ideas?
