yeongk,
first time, i svc at honda sc.. the glenmarie kosmokars. after get the bill, cikoi so expensive lo... check material also same as outside one. some more the service officer want to kapak me for my broken side mirror. u guess how much he say the mirror (1 set auto 1 side only)? he say RM1K+ woo.. can believe aa? finally i never send to there oledi. i bought ori honda side mirror from outside only rm380 + install.
stromberg i installed in my last wira. before and after got feeling difference.. example, before, when climb hill, normally i need to off aircond to get power. but after install, no need off aircond. power increase is marginal lar, not so much.. fuel not so safe.. maybe a bit only. since you get more power, sure u press like hell also.. finally almost same FC la.. unless ur foot not so heavy, i think can save fuel a lot... for me, my foot so heavy to press the pedal to the metal..always 4k-5k rpm one.
stromberg improve by increase sparking frequency. if normally, when ditributor spin, each plug is spark once before air+fuel mixture explode. there is some air+fuel mixture left not fully burn by the one time spark. so stromberg make spark happen more than 1 time..(maybe 5-10 times, im not sure), so MORE air+fuel mixture burns. this can also be done by thicker plug cable..(less resistance, higher current, so bigger spark).
my advice better chg thicker plug cable and use better spark plug (like iridium type). stromberg is ok lar.. some more they say its standard built in volvo cars. should not be a problem. but need to service/clean with WD40... so troublesome..
walane.. so long post.. almost become email. soli lehh. by the way just now screw hit my tyre. cikoi.... tumolo tampal.:sad_smile:
