Looks nice, but narrower passages have higher pressure drops unless offset by increased flow area. Not sure how the pressure drop and efficiency compares with OEM, PRL, etc.
Intercoolers tend to be efficient heat transfer wise, so the law of diminishing returns applies.
That being said, I...
It's very normal to hear a change in noise clutch-out vs clutch -in. Throw out bearing, clutch, and engine all get loaded clutch-in and the transmission input shaft stops spinning.
This is very noticeable on motorcycles, since you're sitting right over the powertrain.
Unfortunately, unscrupulous importers took advantage of the (under) $800 exemption for vehicle part import invoices. I've read everything is now subject to tariffs, regardless of price.
I've had good luck polishing plastic with Maguiar's PlastX and a microfiber cloth. I'd try that before spending big $.
For light interior and window tint cleaning, I use distilled water with about 6 drops of Dawn dish soap in a spray bottle. Won't hurt surfaces or leave streaks on windows.
Check for stones inside the fender liners and undertrays. I found some when adding sound deadening. You can tap the plastic liners/trays and hear rattling if stones are present.
I sold my 2004 Acura TL 6MT to my son, who subsequently stoplight drag raced it. The car had Pilot Supersport tires, which were grippy in warm weather and both CV axles gave out. The transmission, LSD, and clutch were still fine when he sold it at 200k miles. Luckily, CV axles were fairly...
Wheel hop and/or bottoming motor mounts. Expensive parts banging around. Very hard on the car in the long run. Stock CTR wasn't meant for stoplight drag racing.
If Honda doesn't get enough warranty claims, they'll never fix the tank design.
The coolant tank is an easy swap. I was more concerned with the steering rack fix, but it turned out fine for me.
I'd like to install a metal tank, since it's my forever car and plastic eventually fails. However...
Back in the day, I replaced blanks with aftermarket fog light and cruise control switches.
I find the lighting awesome on the CTR for my purposes, so no need.
Can the electrolyte in our GS Yuasa batteries be topped off? The top of the battery is unlike anything I've seen before. It's not obvious I can remove the top cap without breaking something. The top cap spans the length of the battery.
Its normal to occassionally to top off lead-acid...
Honda UK owners manual shows transmission oil change every 37.5K miles for severe driving or every 75K miles in normal driving.
Due to the Torsen style diff, good to change frequently if tracking. These diffs are hard on the oil.
I've done the 1st change earlier in other cars, but no...
Dipstick is the worst design I've ever seen. Clean off, reinsert and withdraw to read. I can just barely make out the level after that using magnifying glasses.
American Honda offers free oil changes for a while (was 2 years on 2024's). I change my own, but have decades of experience and...
In the USA, 5W-30 is still common in 5 quart jug (USA, not Imperial qts) to to the latest API oil spec. Higher viscosity oils in latest API spec are rarer.
BTW, my car dipstick shows full at 5.5 quarts, so an extra quart bottle (in addition to 5 qt jugs) covers 2 changes. Honda says 5.7 qts...
I used 45 sqft, which was 25 lb of the Amazon Basics material.
Another thing I note: When the doors are closed, they sound like an S class Mercedes vs. a typical Japanese sedan.
I recented rented a 2025 Camry on vacation and it was very tinny compared to my CTR.
I used Amazon Basics sound deadening on the fenders, outer door panels, and spare tire well.
Definite improvement, but no Lexus. High pitch tire hiss is gone, but low pitch rumble remains. I'm not willing to add further deadening, as we drive another, quieter car on longer trips.
