ノーマルのフィルターよりレスポンスがよくなりました。

問題なく使用でき、吸気音がでてやる気にさせる。ステッカーもかっこいい! メンテは少々めんどくさい、施工した後乾かさなきゃならないので一台持ちは出掛けない日に施工するのが良いでしょう

前々から交換しようと思ってたタイミングで、セールだったのでこちらを購入しました。 アクセル踏んだ時に空気を吸い込む音が少し大きくなった気がするのでおそらくその分影響あると思います。

Renault Twingo3に使用 並行輸入品だろうが正規輸入品だろうが結局、製造拠点は同じ米国であり中身は全く同じ物なので安いに越したことはない! 交換前K&N 33-3043 交換後K&N 33-3043 汚れた旧33-3043をK&Nウォッシャー&エアゾールオイルセット99-5000(HTR2.1)で洗浄、乾燥、オイル塗布後、新品同様になった旧フィルターを次回交換用として保管。2個を交互に使う事により半永久的にK&Nオンリーで使えるので使い捨て紙フィルターよりエンジン保護に貢献してくれるはずです。吸排気サウンドは楽しめませんが純正クリーナーボックス経由が一番安全安心でスロットルボディの汚れをなるだけ防げるしTurbo車は綺麗な空気&混合気が命ですから湿式オイルフィルターで長く車両の健康維持が可能かと思います。

the product is great as per usual. K&N should look into designing colder intakes for Volvo cars especially the S60 and V60 there is a market building for performance volvo parts and slim pickings at every turn. its pretty much all quality products but supply and demand and the Volvo name add up to some pretty steep prices as it goes for a good brand filter to intake and 3" cold air intake kit will be at least $1000 Canadian add hundreds more for coatings... just my opinion plus I was searching allover for the flat K&N air filter which was difficult so I order from amazon but 2 hours later I found the same filter for $10 plus LESS at a brick and mortars store.... in Edmonton called MOPAC PERFORMANCE and the had my K&N filets the self for less money.....

Tengo una Volvo xc60 2 litros turbo y este filtro es el complemento ideal para que el vehículo tome el aire que necesita para despegar con singular alegría …. Súper … lo único malo es que no trajo calcomanías

After being informed by a Honda Dealership that I needed to replace my air filter (and them informing me that they wanted to charge me +$75 to do this), I decided purchase and install this K&N Air Filter in my 2006 Honda Civic EX in an effort to save money. Included in packaging: 1. K&N Filter 2. A sticker to place on your air filter housing that reminds mechanics not to replace and throw away your K&N Filter (the filter is reusable: simply wash, dry, and replace when dirty). 3. Instructions and care information The installation of this filter was extremely easy and took less than 5 minutes to complete (no tools required). Upon installation, I immediately noticed a slight change in performance in my Honda Civic. I am averaging 1-3 additional mpg per fill up after the installation. The true beauty of this filter is that it is reusable. Whenever you are due to change your air filter, simply remove your K&N filter, run water through it in order to remove the dirt build up, and let it dry before reinstalling. Buy this filter and you should never have to replace your air filter in your car again for as long as you own your car ($ saver). If you are not a "do it yourself" type person, I would still buy this filter on Amazon and have your local mechanic install it for you. Shoot...hire me and I will install it for you (sorry I don't come cheap)! Sure this filter is more expensive than most other filters out there, but if you purchase this filter you should never have to replace your air filter ever again. This filter will not only save you money in the long run, but it will improve your mpg performance (roughly 1-3 mpg for me). I highly recommend this filter!
