Boy was it not obvious where I should place my post. Looking to expand my knowledge of the 2023 1.5T in my CRV I first went to the obvious place, a CRV forum, and was told to look here because CRV owners 'just drive 'em' :). A few months of monitoring and yes, the most such owners appear to worry about is Apple Play.

But I'm an inventor by experience, have made my living that way all my adult life; and more recently a researcher and author. None of it in automobiles. But when I went to JC to study to become an auto mechanic and eventually found myself in the college's most advance auto class, the other men there on the GI bill chose projects such as measuring oil viscosity and I borrowed the scoo's Rajay turbocharger and built a turbo system for my Pinto with German 2.0 OHC crossflow motor!

Many decades later I've fiddled with my months' old CRV and came up with this, attached.

Fun to consider, and surely not suited to sub zero temps that could include ice, sleet, and snow. The Honda air box itself will handle locusts and even rain because the heavy stuff has to fall below the air filter that is a K&N in this cas, then blow up through it to the engine. But it does seem plausible that changing from hot, turbulent air from the radiator (the rubber panel beneath the factory intake) to cool, laminar air from the forward edge of the hood/bonnet, plus velocity of the vehicle traveling 110 km/h freeway speeds (65-70 mph) for further cooling, can only lend an assist to the factory setup.

Won't be doing any more than this because it's in factory warranty for a long, long time. Have to say I'm disappointed in the modern ways, such as the OBDIi readers, when it used to be an old-school boost gauge would consistently give an answer any time, every time; such as on my Ford Mustang SVOs (had three). 6 psi boost max, anyone, according to the OBDII readers? Unlikely, eh? Mine is the L15BG (FFV) Thailand motor and goes like a scared bat.

Feel free to say 'won't work' because I have only my seat-of-the-pants meter given that my two OBDII readers give no results that I'd consider accurate or reliable! And the local dyno chap sneered and said to me 'we only do race cars'.

Ah. Great question. The rubber moulding at the leading edge of the hood/bonnet, ahead of the factory snorkel, has been cut away. This then provides an opening that is as wide and tall as the snorkel's mouth itself, for cold laminar air to flow directly to the snorkel then to the factory opening. Dunno what direct entry of sub-zero temps would do! Probably nothing but then I don't have to worry about such as I am in sunny SE Queensland Australia where we keep snow, ice and very low temps in the mountains of our southern States! At 100 km/h on a 7 deg C day the math says air temp would fall to zero here but that w/b rare, and lots of heat in the inlet tract after the compressor!

Have experienced plagues of locusts in both southern Victoria, and in central California. People go so far as to cover their entire grilles with open-mesh shade cloth to avoid clogging their radiators. Don't get these swarms here where I live. That slit at the forward edge of the hood/bonnet is mighty slim, along the lines of a knight's helmet (which blocked all but a knife, which is why a knight didn't want to go down in full armour, he couldn't get up to avoid a knife blade, armour too heavy for the man to rise).

Looks great and good idea. Now the prl intake fits the crv as well and draws the air from down by the fog light location behind the bumper. I have it on my girls car lol. Good luck on the dyno hunt

Did you make this or buy it somewhere I’ve been looking for the same thing

I made the snorkel from a British company's air duct for race car brakes. Comes in two halves that are then glued together (once it was finalised) with ABS pipe glue. See a more complete tale about it all at the companion thread called 'The Part That Honda Forgot" on this forum. The heat shield that thread is about has made the MOST impact on power; there's an extra 'hook' in acceleration now. It's attached with the existing screw of the headlamp assembly, removes in sixty seconds.
