The included installation manual has clear pictures and instructions to guide the installer throughout the whole process. The kit does NOT require tuning and does not trigger CEL light. No modification is required during the installation.
Product it great would have given it 5 stars but I would have liked to have had them include a hose clamp but I got it from a auto store though and there was a bolt missing from the box for the intake bracket but nothing I couldn’t get from a home improvement store. I recommend switching to a dryflow filter because the electronics are sensitive and the oil from the non dryflow filters could potentially ruin your map sensor so why take the chance.
