What did you do to your Integra Type S today? 🙋🏻‍♂️

[Victorofhavoc]

I read a thread on FB recently that said the Infinity wasn’t very loud, but that person didn’t do the inlet tube at the same time…I don’t know why you would do one and not the other, but that might have been why. Others that have commented in the past have said the Infinity (the full system) is loud af. I hope they’re right, cause I’m about to pull the trigger on it.

The stock intake has a resonance chamber and two flex pipes (that kill sound). You're also working through denser paper media. Remove the resonance chamber, replace flex pipes with silicone hoses, and toss in a panel filter and that's pretty much as loud as it will go. Sure you could rip off the airbox or stick a cone on and that would go a bit louder, but splitting some hairs there.

I don't get why you'd get the intake but not inlet pipe, either. From a performance standpoint, I would argue the biggest component is that inlet pipe... It needs heat shielding from the turbo and in factory form it's already a problem. There's no "flow restriction" I can see for the stock turbo, but there's certainly a heat restriction. I'm probably going to replace the inlet pipe and not the intake soon. Doing a turbo blanket first to see its effects, then will do the eventuri inlet wrapped in gold foil or make my own carbon pipe.

i want to to do the infinity design but I already spent money and installed the prl. I heard the infinity design isn't that loud. Which makes me hesitate. If anyone knows if it sounds just as loud as the prl i might! Then i have to get another tune :S

So I can't necessarily comment on what it sounds like vs the PRL, because I haven't heard the PRL. But I have the ID intake and inlet tube, and think it sounds fantastic.

I had some inflated expectations when I installed it of having a B18C-style "honk" but that's just not practical with this car with a turbo in the way. What I got was a moderately increased amount of "actual" intake noise, but a whole new world of turbo and blow-off noises.

I can't imagine the PRL would amount to much difference given the similarity in overall design, but I could imagine a true open element a la armaspeed might give off more actual intake noise. But if it's mainly the turbo sounds you're worried about, I'm pretty confident it won't disappoint.

Also worth noting was a substantial difference in midrange and upper-end punch. Dyno results have validated this vs other intakes (including the PRL).

It also looks amazing.

well shoot! i might have to pick one up during the next sale! The matte looks great. I think it will be a nice contrast with all the gloss carbon i have in there.

Idk I think the gloss would look best in your setup but contrast isn't a bad thing either. Either way I've always just sort of been turned off with the PRL design. I know they have a CF option now but still- ID is just more elegant IMO.

The big question is the inlet tube. I don't hate the way the PRL inlet tube looks, it's just a matter of personal preference of titanium vs carbon.

From a performance perspective, titanium is a lot more efficient than carbon at repelling heat so I think the carbon is a downgrade there on the prl setup. That said, the ti piece has an aluminum elbow right on that toasty turbo, so likely the benefit of the titanium is evened out by the toasty elbow. Eventuri specifically claims their elbow has a silicone contact point to reduce heat transfer to the intake piping. While true, I suspect the bigger reason for it is to avoid carbon's "flatness" imperfections and its tendency to crack under higher heat and torque from the bolts.

Good looking piece though, and design wise it makes a lot of sense for efficiency.

Preemptively Installed the PRL coolant expansion tank. My stocker wasn’t leaking but I know my luck and it would have cracked in February and I’d be out in the driveway changing it when it’s 7 degrees.

While I was fiddling in the engine bay, I also threw in some MDR Industries billet aluminum aesthetic bits (radiator cap cover, battery strap, oil cap, and washer fluid cap). Everything fits great and the finish quality is mint. Did I spend money on visual goodies that otherwise do nothing? Yes. Does it make me smile when I open my hood? Absolutely.

Did run to Dallas for the night then back to Austin to pick up my son from camp. Love this damn car really makes that run enjoyable just really could use extra 3-4 gallons of fuel tank ?

How often do people actually have this coolant expansion tank failure? Seems dumb it would fail. I've been tracking mine for the last year and haven't had any issues. I keep seeing people replacing their tanks, though. Seems odd it would fail the way it does instead of just overflow like normal...

Since delivery of the original models, folks had been having to get warranty replacement of the tank due to it cracking; likely from heat+vibrations. I think it was more prominent with the FL5 but it’s the same tank on the DE5

I can just go off the anecdotal data I see in this forum and in the FB groups. Seems to be a weak point, with the same style of failure (seams leaking). If I’m honest with myself, I really just needed an excuse to start prettying up the engine bay. I think it’s a good excuse, though.

It's totally hit or miss. I know guys tracking their cars hard, me somewhat included and knock wood, no issues. I think it was a bad run of tanks, early on in the '23/'24 build cycle, so you just don't see it a ton.

Coolant tank failure is common on the FK8s also.

If it was that common wouldn't they have tried to fix it from one gen to next?

And if it's a factory defect why not make the dealer replace it? Honda can't know what to fix if they don't see the problems coming in...

Many do go this route. Unfortunately they often end up with another leak later down the road. (same part)

Seems like a reliability issue... So with enough evidence that's class action stuff.
