I've driven 2200 km's with the Cortina without air filters, a Friend clocked up nearly 40 000 km's in a Sierra and an Escort with no filters. Never any issues and all the cars have been driven on gravel and snow for extended periods of time. Not bothered at all.
Met one white mk1 Escort and the owner in Hernesaari today. After seeing exhuast manifold that has those extra chambers I walked back to mr.M and asked does he know you
The damages of the crash could have been *lot* worse, apparent damages so far include:
? Windscreen cracked
? Passenger side front fender is extremely bent
? Passenger side sill is pushed in quite a lot
? Bottom of the A-pillar has been pushed down and the pillar is slightly bent at the very bottom.
