saken lang IMHO, I find it most practical to change the air cleaner into a cone-type filter..I'm using only Simota on my 7g and yet the performance of it is quite significant and manifested so to speak. I've been using this for almost 4 years narin,..still the filter has no signs of wear and tear,..(religious kasi ako maglinis ng filter),..rather than buying an OEM..gastos lang.. ..opnion lang po mga bros,..ty!
