You guys rock! lol
Thank you all for your inputs again!
As for the springs I will just wait a little longer and get the coilovers in the future
I have about 44,000 miles on my FX and soon or later my shocks and struts are going be worned out and I will end up getting those replaced...
So why not just save up a little more and get coilovers later since shocks/struts/springs/labor will cost about getting coilovers

Sorry Aerobfa..

As for plenum spacer, I've been wanting to get one, but why would it decrease MPG?
Some say there is an increase in MPG, but some people experienced decrease in MPG.
I have the intake and CBE which it suppose to increase the MPG a little, so I guess even if the space decreases my MPG, it will somehow cancel out each other...
Can anyone else verify and explain whether the space will decrease MPG or not?
Oh Jumbo, can you explain what is shift kit and how it works exactly?
Do you have a picture of it? Any brands you recommend?
Thank you !
