3ZZ FE Intake Manifold

[Dennis1311]

I heard that you can change the intake manifold of 3zz with the one from 1zz for a little hp boost and that they are “plug and play”. Have any of you did this change and what could go wrong? Thanks 🙏🏻

If it does fit it will over fuel if anything, fairly pointless without improving the air flow (air in, air out) so exhaust/manifold then you need a remap to add fuel/sort out the map

if you want to drive faster sort out the suspension, new/uprated poly bushes to tighten up the car, then tires and brakes
