So, this is my '89 ES T1 5 speed, this is the way it was when I bought it. Previous owner was a younger guy who this mod, kinda half cobbled together IMO. He said he found the layout on the internet from other people who do it this way, I don't know, I've never seen any pictures of a TD looking this way. Anyway, I'm in the process of taking out the mix & match silicone/aluminum configuration and going all silicone (with the exception of the pipe with the BOV). That's only half the battle, I haven't been able to think of a way to get the intake out of the engine compartment, or should I say a way to get it drawing in outside air instead of hot under-hood air. I have a stock airbox that I can switch back to, but that's a last resort right now since I do kind of like the performance this seems to give and the flexibility of the after market BOV. So, I want to know if anyone knows a way to run the ducting so it's pulling cooler air from outside the engine compartment. What air filter to use, what piping, what arrangement ect. ect. ect.
