Xj40 1988 throttle body

Hi all , Just a curiosity , is there any reason that the bellows from the MAF to the TB has to be corrugated or can i use the appropriately sized smooth hose as a replacement .

Flexibility, the air filter box is fixed to the inner guard while the engine can move.


Robin , yeah , never thought of that , would fall off all the time . HHMMM , well that’s sorted then . Thanx

BTW talking of Throttle Bodies, I’m not sure what size the 3.6 has but I know the later 3.2 had a smaller TB than the 4.0
One trick with the 3.2 was to use the 4.0 TB for a slight increase in performance.
