Ive had xentex's on in my camry in the low and fogs.. had them in my 08 cbr hi/low.. 08 busa hi/low.. and currently running them in my 11 busa hi/low. no problems at all.
2+ years, 1000s of wheelies, an off road adventure and xentec stll works today. Never a single problem.
I just ordered a H4 bulb to fit the stunt bike.
wow seems both are hit and miss. prob try xentec one more time before switching. thx guys
