I'll reiterate this again like it has been before... Take a 3" intake tube and filter.. The engine is only going to take in a certain amount on its own, but with a larger intake, the engine has a larger volume of air to pull from.
So compare a 4" intake to that 3"... In this situation, the engine has a larger volume of air to pull from with the 4" compared to the smaller volume of the 3".
4" tubing and filter as large as can fit.
No bends preferably, if you must: lower angle results in more flow.
Most people run a 22.5* bend off the TB...4" intake...9" filter...
Everyone forgets to make shrouding for it
It's still gonna get hot.
Not like it helps.
Suck air from outsides, not insides.
HAI effectively decreases boost so people don't blow engines so often.
Flows more though. Iat is higher, more likely to detonate.
Yeah, agree.
whats a scangauge lol
