Mod for 320i???

[TripleM]

galant1688,

1/3. With regard to air filters, they can be in various forms, either open box filter (like using a cone filter, which is referred to as CAI ) or with close box filter (replace the stock drop-in filter with and after mkt one like KNN, ITG etc )

The pros n cons are generally felt in the torque response curve.
By removing the stock airbox and replace it with a cone filter, ur front end torque will suffer a little but mid range onwards is better vs stock.
If u retain ur stock airbox, however, ur front end torque will be better but mid range onwards won't be as good as the CAI above.

In terms of noise level, open air set up will be a little louder.

2. Spark plugs...some after market ones can improve the throttle response a bit...The highly acclaimed Iridium is one of them but if u want something that is long lasting, go for platinum ones.

3. Exhaust...
Generally after mkt ones are louder than stocks..Many think the hp gain is just a buttfeel but some are real gains.

Gd luck and pls be reminded of warranty issues esp if engine component has been replaced with after mkt ones, eg spark plugs.

Cheers

close box filter (replace the stock drop-in filter with and after mkt one like KNN, ITG etc )

would there be an increase in noise level, if I replace the stock air filter with KNN drop-in filter into the filter box? Cone filter is definitely out for me, as I do not want noise.

Previous Galant is noisy enough...

want increase in performanc but noise level minimal.

If i opt for Obit, the bhp would incrase but would the noise level increase? Wat about UUC pulley, would the noise level increase too?

Very careful on my mod now, as I do not want to compromise noise for performance

Re: Mod for 320i???

If you have other suggestions, please also voice out e.g. I heard there is a computer chip available for our ECU and HP would increase to 200+. Owners of VW Passat also uses this to increase HP.

I would base your feedback to plan my mod... Ke ke ke

if there is a chip to increase bhp to 200+, i guess the shop who sell will be loaded. 30+ bhp from chip (NA), not possible. go for supercharger if u look for 200+ bhp region.
how can UUC pulley, n obit increase noise level ? :thinking:
go meetup, see others bro cars...

your mods will only give you about 10bhp realistically. see if the money spent is worth the increment.

You'd be better off spending the mods on your suspension and trying to lighten your car rather than any of the mods that are listed above. You can get lightened hoods and boots and door panels relatively inexpensively nowadays. Cheers!
