I am thinking of getting a K&N cold air intake for my Silverado. I am wondering if anyone has purchased this one and what your thoughts are. Also, will adding an intake void the warranty? https://www.americantrucks.com/kn-53silverado1500-series-77-high-flow-performance-cold-air-intake-77-3110kp.html

I just bought a 21 Silverado RST and About 4 months after purchasing it I have started to notice a rattle/squeak coming from the driver side door frame. It is extremely loud. I have tried shaking different pieces of plastic but I have not been able to recreate the noise. It only happens when driving over bumpy roads. I am wondering if anyone else has experienced this and if so, were you able to find the source of the noise? I am assuming it is a piece of plastic that needs to be tightened. Thanks.
