Air filter housings - Are they an add-on, or...

[BassORama]

Hello, I have been shopping for a new zero turn and I have noticed a variety of engine options and also some larger air filter housings attached. Are some these after market items, or factory installed? If someone does install an after market housing/add-on, does it effect the warranty?

Thank you,
Matt

You are probably seeing the heavy duty air cleaner system. They are engine OEM factory installed.

changing the air filter after bought might require changes to the carb.
If you want to know why PM me as explanations are not allowed.
