This refers to the Accessory belt pulleys, and modifying them in a way to increase performance
There are two available pulley sets for our car. Either stock size, or underdrive. They claim to increase torque slightly, and throttle response. We will go over both solutions, and if you are interested, you can get the set that is right for you. First, we will discuss the controversy behind this mod.
Understanding the controversy
It is important to note that these mods are another controversial topic as to whether they really affect the performance in a way that is desirable. Part of this stems from harmonic dampening. The aftermarket solution apparently does not have rubber on the wheel, which leads to squealing when the accessory is under heavy load. AKA air conditioning. Also we dont have 100% proof that this is safe for our engine.
Your accessory belts are running the entire time you engine is. As your RPM's go up, so does the RPM's of your accessory belts, which are ultimately "parasites" to your engine. The pulleys that are spinning have a certain amount of mass to them. The idea behind aftermarket pulleys is to reduce this weight. However, engines that are not internally balanced can can have catastrophic problems due to vibration of the flywheel shaft because the pulley is now much much lighter. It is claimed that the J35 engine is in fact internally balanced, but some still fear this may not entirely be the case, and we may suffer the consequences of this mod down the road.
Benefits. The benefits of this mod are said to be pretty considerable by some, and others, not at all. Most likely throttle response will appear to be faster because the engine can now spool up the accessory belt much faster, so if you are in neutral and give the car some gas, your rpms should jump much faster.
In this set, the pulleys will use less engine power to spin your accessories. In turn, you will free up some power, albeit not much, at the cost of generating less electricity from your alternator, and slightly more difficult steering as your power steering pump will also be moving slower. This setup is not recommended if you plan to have, or have after an market stereo systems in your vehicle, though some claim success even still.
In this setup, the accessory load is not changed, but the pulley is lighter, so your car will have a slightly faster throttle response without any consequences.

Now that you've read the pro's and con's, here are the known choices available for our vehicle.

Currently there are no tunes available for the V6 Accord, but we are hoping K-Tuner will offer a solution! When news is released, this section will be updated.
This section is for everything related to the Transmission itself (Bushings / Shifters / Fluids / Clutches / Flywheels / Ect.)
Note: The V6 accord comes in both automatic and manual options. I will start off with all of the sections and information pertaining to the manual. The automatic, I know nothing about, so I will add it in its own section at the end. I will need someone to help me. Thanks.
The manual transmission on the V6 accord is prone to a lot of problems, and when you are increasing the horsepower and torque of your ride, the problems become much more prevalent. Hopefully this guide will ail your troubles if you have any. If not, then its important to make sure you keep your gearbox running at its best. So we will start with maintenance before performance.
The trouble of the third gear grinding....sound familiar? Read on. Even if not, its good to keep up on your maintenance.
Gear grinding is a very common occurrence with this model, regardless of your manual skill level you may have troubles. So here is some things you can do to troubleshoot and hopefully fix the problem.
GM syncromesh friction modified. Highly recommended across the board. Its everyone's favorite. I haven't tried it because quite simply I cannot find it! Your transmissions fluid may not be in good health, or even just really low. If you cannot find GM's fluid, go to honda and get the MTF fluid from them. Their newer version works really well. It'll cost about 40$.
You can do this procedure yourself very easily. If you can change your oil, you can change your Manual trannys fluid. I will link a guide later.
Note: For maximum effect, I recommend changing your MTF fluid again in another month or so. This will ensure that all of the old fluid and deposits are removed from your transmission.
You may have noticed that your shifter has "slop" when putting it into gear. This is due to the shifter cables connecting to the transmission via RUBBER bushings. You can swap these out with two aftermarket solutions. Both will work equally. They will greatly improve shifter quality, and reduce chances of gear grinding. This is a very highly recommended mod.
These are also available for our vehicles, but it is completely unnecessary. You will notice no difference if you use these or you don't. Considering the OEM base bushings will never go bad, you will never need to concern yourself with these. This is my opinion.
This is available for our vehicles, and while expensive, it is a very worthy mod that will improve shifting quality about as much as the shifter bushings will. You can install a weighted shift knob at the stock height, so your experience will feel similar to stock, but each shift will be very precise.
Weighted Shift Knob
Again, will dramatically improve shift quality. Once you install a weighted shifter, you will be unable to go back. The added weight does not create more effort for you, the driver, instead, it lessens it considerably.

Clutches / Flywheels
Not much seems to be known about installing these on our accord and their effect. The only thing known about the flywheel available is that it is lightweight aluminum, and that it is best not to install it if you chose to install aftermarket pulleys.
Steel Braided Clutch Line
Replaces the OEM Rubber section only. This enhances engine bay appearance (If you're worried), as well as improving clutch response slightly. I plan to do this mod soon, and I will give you my feedback, as well as, (hopefully), a guide.
This section is for everything related to the chassis, both sedan and coupe (Sway bars / Tower bars / reinforcing bars) / ect
The vehicles handling is probably the weakest link for the Accord as a whole. We users often refer to it "handles like a boat", due to the vehicle sway when entering sharp turns. Good news! There are many aftermarket products for our vehicle that will greatly improve handling!
I will pull information directly from the product page of throwdownperformance.com
, as well as recommend you check them out for these aftermarket parts!
Rear Sway Bar
This is the most popular upgrade for the 8th gen Accord. You have a couple choices, but any of them offer considerable improvement. This bar is installed between the rear two wheels, and contributes a good majority to the sway problem. If nothing else, upgrade this piece to improve handling!
There are two sizes available. A larger bar will cause a larger "shock" to the car and its passengers when you encounter bumps and other anomilies on the road! Choose the bar that is best for the area that you live in. Reviews are positive equally from both users, though some wish that they purchased a larger bar because they didnt find the tradeoff bad.
These connect the rear sway bar to the vehicle. If you upgrade the size of your rear sway bar, you may want to upgrade these to be larger. The general consensus is that these are not required, but recommended if you plan to have your car a very long time.
Front Tower Strut Bar
This is a brace that is located on the top of the front two struts, and again, contributes to body roll. The stock EX-L version of the accord has one OEM, but even still, it can be upgraded to a slightly better one from Ultra Racing. Those who do not have a front tower strut bar have noticed a nice difference when installing these.
The weight transfer and force gathering on one side, causing unstable handling and increasing body roll
The force will spread out by Ultra Racingís strut bar and lower arm bar, stabilize the car and provide solid handling
Front Sway Bar
Same as rear, but only upgrade this bar if you have upgrade your rear bar! Otherwise it may effect handling negatively and create unsafe situations.
You can order this bar from Ultra Racing, or for a fraction of the price you can use Acura TL parts, but will require you to make some minor modifications to your vehicle! View this thread for more information on the install:
