Try this

If you want to use any variable inside the where closure then you have to pass that variable inside the use($variable)

public function show(Request $request, $id)
{
    $products = Product::with('features')
        ->whereHas('features', function ($q) use($request) {
            return $q->where('id', $request->sty);
        })
        ->where('category_id',17)
        ->get();
}
