No issues out of the box; filter fit right in place within the factory Honda box. I can tell an improvement in power when I step on the gas, which is needed out of a 4 cyl engine. Have used K&N Filters in my V8 truck with the same increased response. Great product, no complaints

I just received and installed this new engine air filter and K&N asked me to rate the product. So far it fits well in the air box and has not thrown a CEL (2 weeks/500 miles). Did not notice any inconvenience so far. Purchase experience was great with fast shipping. This is the 10th K&N replacement filter (for 10 different vehicles).

Excellent air filter. I can feel the horse power change and see the gas mileage increase.
