Rob332 Posted April 7, 2016 Share Posted April 7, 2016 Hi guys So I fitted a plenum spacer to my 03 DE. The car is sounding a lot louder. I would expect a louder induction noise from outside. But was anyone's z noticeably louder inside the car as well ? Quote Link to comment Share on other sites More sharing options...
Irn Bru Posted April 7, 2016 Share Posted April 7, 2016 Can't say I noticed an increase in noise when I fitted mine, I do have a loud exhaust though. Do you have the standard air box or an after market air intake fitted ?. Quote Link to comment Share on other sites More sharing options...

Adjusted it to give clearance and all is good now. Took it for a spin and there is definitely a gain in mid range torque. Im Impressed......nearly as good a mod as my stubby aerial 1 Quote Link to comment Share on other sites More sharing options...
