Like I said previously the car was throwing a code, po100, so I got some MAF cleaner and ordered a new filter. Super easy process. Remove hose clamp to the filter and remove filter. Unclip MAF plugs, carefully remove avoiding touching the hot wire. Spray the MAF cleaner all over it and wait 15 minutes for it to dry out. Put the MAF Sensor back in, install new filter.
Considering the car already had the cold air intake beforehand, there was still a noticeable difference driving around. The car lived on a gravel road for many years, and revisited the same for years after so the filter and MAF were just caked in dirt, no wonder it threw the code. Throttle response is snappier, engine sounds like it's breathing better, hopefully the mpg will improve a bit too. Pretty happy with it overall despite this being maintenance oriented as opposed to an upgrade.
