Guest 4294r Posted November 13, 2014 Share Posted November 13, 2014 Hi folks! I have a huge ITG air filter on my single turbo, I've been told this might me a bit restrictive? Would it be worth changing and if so would I need a re-map again? Quote Link to comment Share on other sites More sharing options...
chrispot Posted November 15, 2014 Share Posted November 15, 2014 If the air filter is a restriction I would change it, and if your car has been mapped with map sensor fitted (more than likely a map than a maf) then it would be a good idea to have the mapping checked. I don't know anything about itg filters, but I would connect a manometer just after the air filter to check air filter pressure drop. Or just buy a big k&n and then get the map checked.
