ok if i upgrade 2 denso iridium 0.4mm...n Works engineering air filter ...how much of power gain there?

Not too sure cos never dyno before.
Air filter will provide gain of 2-4hp on high end rpm.
Denso Plugs will provide smoother acceleration and higher torque due to high powered combustion, but power increase estimated to be 1- 3hp. But high rpm engine rpm would be smooth as nearly 0 misfiring. So better FC on highway..

need some feedback from sifus..

this 3350UB how much improvement will it gives to the stock speakers on Persona? Let's say I want to keep the stock speakers

Im not sure exactly, but what i can say from my other experience of upgrading to pioneer is the HU gets better reception, sound is slightly clearer with more tuning function.. Pioneer are reknown for their HU. It comes with 2 RCA preout also.. can play with AMP.

LOL.. i think he meant upgrade TO denso plugs.. IM language mah.. XD

2morow i will go service my car, for 5k km service, can i bring my own lube at that interval? or have to stick wif their warranty schedule? decide to use castrol semi...

No worries lah.. We convoying to the top only.. Not racing up there..

i mean "TO"...sorry

Oo... haha soo embarassing

Whats ur mileage now? defintely can go for service every 5k if u awnt lah.. but its more of a waste of money to me cause u pay twice for labour and changing parts.. Not to mention the time involved too..

mileage 5k km only..

so in ur opinion, is changing the speakers first better, or change the HU first?

Electric engine ma.. But the fc is something I won't complain about la...

Dun blame the fuel.. Blame ur right foot..

Depends on u lah.. Of cos it'll be better than stock, but it's whether if u can detect the difference with ur ears or not oni..

5k service better use semi.. and service at 10k again, cos engine is new and tight. There will be a lot of debris in the breaking in process.. Once after 10k km the engine will be super smooth, so u can extend service mileage to every 10k ady. Use castrol magnatec at ur next service. Guaranteed no regrets.

Speakers first.. Our current speakers are not good enough.. cos its component 6" speakers, it cant differentiate the bass and treble properly. FOr the HU u can buy a decent 2way 6.5" front crossover ady. Get 3way front crossover if ur budget allows. Then get 2 way crossover for the back.. HU unit can upgrade after u get good speakers and amp set cos our blaupunkt is not that bad HU either.

HU first. Then speakers. Then amp.

haha.... let see what my mood will be this saturday... so which service centre i should go that can bring own lube near shah alam or selayang??

Our original HU only got 1 output. Can masuk amp but need to add Y cable n the quality won't be nice.

Haiya the response is so good.. And the engine very willing to rev from 2.5krpm to 3.5krpm very willingly.. So automatically i pull to that range lah.. haha.. Normally i shift gear below 2.7k rpm one..

Going convoy dont race lah.. Later whoever shoot up u paintball their brakes.. GG.com when they want to brake later.. XD
