[tomo v6]

any cold fed and sealed induction system is better than having a std pipercross/kn filter dangling around an engine bay sucking in hot air.

Yes they are suberb i have one on my Xe corsa and its lovely Slight Crawl to it..Not as noisey as a open induction kit but they are defo worth the money..
I dont get no heat soak or flat spots what so ever..It really loud when u take of the cold air feed but thats defeatin the point of a sealed induction kit isnt it!!!

As for performance wise yes i have noticed a big difference in performance with the Xe...Much better than them open crap induction kit..
