Are there any air filters out there that fit a Nick Williams 103mm tb? The flange OD is 4.25". If not what are people using?
Thanks

 

Whatever one fits on the inlet of the turbo! 😉

 

Funny, there is no turbo, just a Whipple with a TB!

 

Sounds stupid but you may need to warm up a 4” air filter and stretch it over. If you have space there’s plenty of 4.25-4” adapters and then you could use a short piece of material to attach. Afe has an air filter builder thing on their website I use to figure out what will work for me.

 

Thanks, Quito195

 

Find a filter kit for another platform that will work with modification?
Usually when I see a kit for PD blower cars, the intake tube is larger than the TB opening which I assume is to accommodate the volume as well as smooth out the airflow.
