8-hour layover in KLIA - Possible to visit KL?

Hi! I arrive at KLIA around 11.15am and have a flight out at 7.20pm. Curious if that’s enough time to exit the airport and visit KL (have a meal/coffee)? I know it’s about an hour out each way but I’m uncertain how long it takes to go through immigration and how hard to book rides.

I also need to leave luggage in the airport and check in later because I’m flying with different airlines.

Appreciate any insight/tips/watch outs.

Thanks in advance.
