Discussion thread Anyone tried the Amazon Thunderstroke “Stage 1” air cleaner copy? About $380 cheaper than Indian’s
I came across an Amazon air cleaner listed as:
“High Flow Cnc Air Cleaner Intake Filter For Indian Chief Chieftain Dark Horse Classic Springfield Roadmaster Chief Vintage 2014-Up” from TOPRAMETAL.
Visually, it looks almost identical to the Indian Thunderstroke Stage 1 High Flow Air Intake (minus the Indian logo), but it is about $380 less.
I already have a Dynojet Power Vision 4 with a Fuel Moto tunes, so my assumption is that I would not need the Indian calibration card. I should be able to install the intake, send Fuel Moto the updated configuration, and load the appropriate revised tune through the PV4.
Has anyone actually installed one of these Amazon versions?
I am mainly interested in:
- Fit and finish (is this product junk?)
- Any air leaks or mounting problems?
- Issues with tuning the bike afterward ?
I understand that the Indian part comes with support and the ECM calibration but nearly $400 is a significant difference for something that appears identical. I would be interested to hear from anyone who has firsthand experience with this intake or another version from the same seller on Amazon.
