lloydy 3 Report post Posted December 28, 2016 So Im not to up to it yet with using this site and tried a search but didn come up with too much. I guess the general add more air flow more air rules apply but just looking at what others have done and where to get bits for my 06 630i. Is it worth doing a whole cold air intake or just going with a K&N? is there a supplier in nz who wuold do a set of headers? again struggling to find something. any other exhaust mods should I look at doing like hi flow cat, hi flow rear mufflers? what model coilovers have people got and like the feel of? and lastly who would you reccommend for a tune? I dont have endless pockets of cash but in not on a hard budget either so looking for best bang for bu k but wont skimp on the important bits. Quote Share this post Link to post Share on other sites
zero 1162 Report post Posted December 28, 2016 I would imagine a tune would be where its at. Gavin at High Velocity isn't cheap but widely considered the best. Quote Share this post Link to post Share on other sites
