snorkel performance

Where is the standard air pick up? A bra is all I need, at my age am not looking for that much excitement..but then again if it had torpedo tubes....(tic)...silverback

Have a look through the forum archives. I know the landcruiser owners online (LCOOL) website has good info too. Basically pros: cleaner and cooler air; less obstructed airflow into engine; safer doing deep water crossings.
cons: cost.

Not necessarily agree. After fitting snorkel my 1HZ + DTS turbo, breathing feels much easier. Yes there is some plumbing involve, but standard intake in 80 way too obtrusive and it is almost impossible to make it worse. Although main reason for snorkel (as name suggest, actually) to make safer water crossing, also it is greatly improve situation in dusty environment, particularly when going behind other vehicle.
