I'm using the shortest 4" opening AEM filter. The circumference of the MAF is a bit smaller than this and I had to use some gasketing to make up the difference to get a tight seal.
Also had to loosen the lower clamp for the intake tube and rotate it a bit to get the cone filter to fit in the space shown.
I'm not claiming that a cone filter by itself will give more power ... just on my vehicle with its mods it produced a statistically significant increase in measured power. |
Sorry to resurrect an old thread and comment.
I don't have data to back this up but I noticed a significant reduction in power from a standing start with the cone filter. It was so noticeable I was thinking there was a problem with the smaller turbo. But it was producing boost according to the monitoring (by another forum member) using one of the BT tools.
Do you have a graph with pre and post to compare the power between the 2 setups. Your configuration and setup might be more accepting to the cone than mine.
Want to put the cone back in but not at the expense of low end power. My guess is heat soak at a stop but lack any hard evidence.
Some things to keep in mind. I am totally stock with just a catch can install.
Cheers.
