Audiovisual demonstration of Subaru BRZ, WRX etc/Toyota 86 Boxer 4 cylinder engine firing order

This video demonstrates the firing order of most 4 cylinder boxer engines. Firing order shown here is 1 3 2 4. This firing order is used by the FA20D in the Subaru BRZ and all other Subaru boxer 4 cylinder (H4) engines. It is also used by the 4U-GSE in the Toyota 86. The same sequence was used on 4 cylinder boxer VW engines but with a different cylinder numbering system. 1 4 2 3 is the other possible firing order for this engine but I am unaware of any engine that use this firing order.
