bro do u have door wiser installed because previously i noticed the same noise in my car until advised my friend. Once removed the sound is gone. I often see people complain bout engine sound in cabin, but isnt tat what turbo cars is all about hearing it when we accelerate?

Have fun guys having kuga for more than a year, often speed with my bro in law who has CX-5 2.5 but nvr lost to him. In highway still managed good fc bout 9l/100km(tats the best achieved). This is my 2nd turbo car after golf GTI because turning into family guy but yet still fun to drive like hot hatch. I have a friend often travels to UK, so wen he returns he will buy me the performance liquid to add on fuel which gives good power (not much but noticeable). Add ceramic liquid with ur black oil u will heard less noise and smooth engine at higher rpm.
