Carbon Filter RWHP?

They aren’t catching carbon but rather they contain active carbon that absorbs fuel vapors.

Has there been a case of anybody getting their warranty voided because they removed the carbon filters?

Not on the S550s. Shops won't even know its missing unless they go hunting for them.

But you got inline traps…

it would be simpler to swap the accordion tubes for something a little smoother and then just swap back if you have to visit an unfriendly dealer, but then again no real reason for them to go poking around in there unless you throw a code.

The carbon traps do not filter air going in.

Nor do they trap anything coming out

Has anyone actually data logged to see if the removal alters fuel trims?

Gains aside I just enjoy intake noise.

I can use a 6G car as an example. I suspect a 7G car could be affected in the same way.

In the 6G, removing the trap itself resulted in a general gain of 10 HP.

Supporting the trap is a tube; this tube sits inside the intake tube. The tube within the intake tube can be easily removed. The effect is an increase in overall intake tube volume and surface area.

Removing trap while keeping tube-in-a-tube: 10 HP. Fuel trims remained in range.

Removing trap and inner tube: 10 HP. Fuel trims were at the maximum. Engine could not adjust further.

The HP gains were in-line with expectations. Earlier cars, pre-trap, their window stickers, noted a 10 HP difference.

As to the fuel trims, with nothing else to be gained and the unwanted lack of further adjustment, the inner tube was kept.

It's been a while since this thread was bumped. If there is an inner tube in the S650, I'd expect similar results, with respect to fuel trims. Taking the trap out itself, trims change, but continue to stay within a range that allows for further adjustment by the PCM.

The new ones are just coiled inside the intake tube with no insert. Just makes me wonder if the area of the trap was worked into the flow rate of the MAF like the tube was on earlier cars. More so because I think most of the reason for the dual TB was to offset emissions restrictions.

There is a sleeve near where the filter box connects to tube. This needs to remain in or you could have MAF issues

Gasoline vapor is mostly carbon. I really don't care. It's time to fire the EPA anyway.

Sadly the damage has been done.

As much as any of us wish things would change if the EPA was gone it wouldn’t.

But would the carb be valid without the epa?

The EPA is there FOR US automakers, they have to have ridiculous strict guidelines to meet or other countries would be able to undercut them with lower cost vehicles…

Everyone would be driving brand new $2k tata nanos

But purchase $1k phones? Odd how quality quantifies

Add up just all the taxes you pay. ALL the taxes. The amount of your money being wasted is sinful. Carbon is just being moved, it isn't going away. And then there is the EPA.....

Can’t mention the ‘t’ word or politically we find tariffs transferred temporarily terminates taxes.
