G70 Engine Jittering when flooring it??

[Hectic_Cutz]

I got my new air intake Power agency installed correctly. After 1-2 weeks one day i floored my car on sports mode and it starts jittering with the bov going crazy and car starts jittering. i got a random engine light but once i parked the car and turned it off then on, the light went away. but now i idle and have a small surge on my torque in my gauge and the car still jitterings when i floor it. any reason why??

I think you posted in the FB group as well... I'd check /replace plugs before doing anything else.
