Review: Very well constructed and perfect for my 23 GX460. I have used the K&N and this in other vehicles and both have performed flawlessly. Cleaning is easy and I keep the OEM filter to use while this filter is drying.
Review: المنتج ممتاز والجودة عالية وفعلاً فرق معي صرفية الوقود ونشاط في العزم وسرعة استجابة الدعسة تحس السيارة أصبحت اخف في الوزن. ملاحظة مهمة عند التنظيف فقط استخدم منظف خاص للفلاتر الجافه غير الزيتية واغسله بالماء لا يستخدم التزييت نهائياَ فهو مصمم تنظيفه بدون وضع الزيت قبل التركيب وهذا اكثر شي اعجبني فيه لان الزيت لا يناسب اجوائنا الصحراوية يمسك الغبار بشكل سريع ويكتم المكينة.
