No, this filter is for use on a lab scope that does not have AC coupling. The Snap On scope has AC coupling built in and will not need or benefit from this adapter.
It filters out the DC offset voltage allowing a scope to view only the change in voltage.
For example, if you wanted to just view the alternator ripple but wanted to remove the overall system voltage this AC pass filter would allow you to do that. If system voltage is 13.5V with a 200mV AC ripple, it would filter out the 13.5V and only allow the 200mV AC voltage to pass through.

Regarding "accessories to aid with diagnostics" with your 2-channel Snap-on scope.
Do primary:
Primary Ignition Probe for the Snap-on VantagePro and MODIS (AES# 01-18-Snap)
Do secondary:
Universal Secondary Test Lead Kit for COP, DIS, HEI, Dist (AES# 01-10)
Use longer leads:
ST3 "Test Drive" Test Leads for the Snap-on VantagePro (10ft) (AES# 03-760-vPro)
Do low current:
Low Current Probe with Banana plugs (AES# 07-60-bp)
Do high current:
Shielded High Current Probe with Banana plugs (AES# 07-600-BP)
