I completed the air filter project in the evening and kept it overnight for the epoxy weld to get firm, fitted it in the car in the morning and went for a drive in the morning to check the difference.
I am amazed at the difference in the performance using this bigger filter. Car runs like a hot knife in a pile of butter. I never imagined it will make such a "BIG" difference.
Just spent only Rs. 300 on all the material and one hour of my on labour and its making the biggest diiference of all the mods tried by me so far.
I have no words to explain the rise in pick up and change in throttle response.
One more thing I noticed is that the intake is now much quiter as compared to earlier set up.
Attaching pix of the new filter in place and old filter as well for you to make out the size difference.
I recommend this to all who are reading this post in whatever car you are using, just try and seek a bigger filter for cool and surprising change in performance.
