Good day all!

Just wondering if anybody has installed the PRL intake system on their Ridgeline. I'm a bit puzzled since they don't have any performance info on the kit, ie increase hp or torque or even fuel consumption numbers.

Much appreciated

I would be happy if intake noises are louder. It will bring back memories from my 8thGen Civic SI high cam crossover (what mortals call vtec).

This guy installed it and posted a clip in the RL Owners Club in the facebook group and it sounds louder.

I bought and installed it...very easy to do considering usually my brother is the tuber and does the car stuff for me..theres a step by step video on Youtube that breaks it down. The kit ends up giving you 20 more inches of water clearance because it includes a resonator delete cap. The pipe is definitely way less restrictive than the OEM and Im sure its all my head but i feel like theres a little more pep because of the air flow, but the sound definitely got better. Take this for what it is 🤷🏼‍♂️

It must be that guy's first time turning a wrench 🤣
I've used PRL's stuff on other vehicles in the past. I bet if someone were to find a cap for the bottom of their intake box, it'd have the same effect as this setup. You can't tell me there's a huge gain from changing the intake duct into the airbox.

Without performance improvement measurements, the modification may actually have a negative impact while making more noise. The OEM intake is computer designed with resonance chambers which not only making the air intake quiet, but at the same time increase airflow by eliminating turbulence. The mod may look smooth to the buyers eye, but there is no analysis of the air flow change, just human speculation.

Agreed. The OEM inlet to the box has little to no restrictions in it unlike the tube going from the box to the TB and I see no benefit to replacing it unless you want something that looks cool. If people want more noise, capping off the resonators will get the job done.

The only benefit I can see to removing the resonator (aside from super awesome "VTEC go wahhh" intake suction noise) is one less avenue for water to get in if you were to do some intense water crossings. You're right though. Without an air flow analysis, we truly don't know what benefit there is to removing the resonator.

Do you really want to drive your stock Ridgeline through water as deep as the bottom of the air filter box? You will likely cause a flood damaged vehicle.

The only advantage for me would be to clean up the underhood somewhat but it's not worth the expense for an unproven product. As long as the vendor is not willing to post a before/after dynamometer then it's not worth pursuing.

I'm reminded of the mantra "if it's ain't broke, don't fix it".

Maybe someone can't afford a boat and wants to pull double duty with their Ridgeline and 20 extra inches of air intake height?🤷‍♂️
What I don't understand with PRL is that almost any other product I look up of theirs, they have dyno results, but on these 3.5 parts, there's no results posted. And obviously, with no tuning you're not going more than 1-2whp if you're extremely lucky with better conditions than a baseline run. (PRL intake hose, filter and duct all together). Plus these cars aren't driven around at WOT all day so you're gaining noise and a lighter wallet.

after research on this item i finally decided to pull the trigger so I paired the snorkel with a k&N drop in. no silicone tubing. I can honestly say worth the 80 bucks I spent on it. makes me smile when im in sport mode with the paddle shifters. when the throttle is wide open it turns heads. no one expects the ridgeline to sound like that. as far as power goes... seems like maybe 1-2hp gain. not interested in the dyno. mainly just for the smiles. this upgrade is more noise than anything. hope this helps

I’m selling my PRL throttle body tube and high volume intake air duct on eBay. Search for PRL Intake for Honda Ridgeline 2017-2023. Had this on my 2021 Ridgeline sport but going back to stock parts. Only had it on for 8 months. Sounds great but between this and my turbo muffler it was a little too loud on both ends :) under load towing a travel trailer just too noisy with the family in the truck. I need to rethink the exhaust system and maybe buy this again in the future.

Today I installed the PRL High Volume Air Duct.

I was happy to spend $100 for the effort that someone else put into a one and done resonator delete package as it meant I didn't need to waste hours finding correct cap and clamps sizes, etc.

Overall I would rate the quality a 4 out of 5. I had to break out the Dremel and clearance the front of the air duct so that it would mate cleanly with the existing plastic cover at the front of the engine bay.

Value: 5 out of 5. I'm in the stage of fatherhood where time is limited, so the extra 8 minutes on the Dremel was perfectly ok as I didn't waste much more time on a DIY solution. After shipping, they can't make a lot of money on these kits. I'm happy to have someone who is able to make a couple bucks by supporting the Ridgeline community.

Sound: 5 out of 5. Idle and part throttle sounds stock. Full throttle the engine screams. I actually wasn't expecting the full throttle volume that is now present. I figured only short ram would roar like that. Sound is the only reason I made the modification as I can't imagine there's measurable power to be had, so with that I m VERY happy that it delivered.
