Some notes- on AFE CAI Yeah as said the directions seriously need a redo, but product :thumb3: Red Circles, left to right
1. Keep all hose clamps snug but loose when first attaching, you have to adjust pipe to have attachment screw for protective engine cover
2. Brass nipple goes into this brass fitting already placed from the factory for the small 5/32 vaccum hose.
3. MAF sensor be sure to use afe supplied screws, plastic thick washers/spacers and gasket.
4. This brass screw as afe said unscrews off the OE unit then screw onto afe. It’s used as one of the mounting screws for engine cover.
5. Larger vaccum hose goes here. DO NOT mistakenly screw brass nipple here. Did I say that from experience? I plead the fifth.
5. Keep all hose clamps snug but loose when first attaching, you have to adjust pipe to have attachment screw for protective engine cover. Make sure the both rubber fittings are properly placed (one for filter one for throttle body) and clamps are on the units before tightening
I had a problem and called AFE help desk, Brian at AFE was on the phone in 30 seconds and in 1 minute hepled me with the fitting question. Thanks Brian.
Also tundra solutions has a video (youtube?) tutorial for AFE CAI install, found 2 of them on there.
End result, great product, not perfect easy install with supplied directions but with research you can do it on your own. I am one very happy T4R owner!
