NEO.rage,
no, it did not void the new car warrantee due to no cutting of wiring or dismantling the engine. it is plug and play item.


cheeann,
thanks for ur help on explaination... hows ur days? 

enqvistlim,
I recommend you install our RAM 10mm Quadcore(tm) HPPC for your Wira 1.5. RAM 10mm Quadcore(tm) is 4 cores inside while Lotusking is single core. RAM 10mm Quadcore(tm) having resistant at around 0.2k ohm while lotusking 0.4k ohm. the lower the resistant, the better the performance. ori plug cable is around 6k ohm.
yes, using HPPC may reduce the lifespan of spark plug at around 5%.
using iridium spark plug will be an added advantage if using RAM 10mm Quadcore(tm) (as we oledi tested and proven). I can supply and install NGK Iridium IX BPR6EIX-11 for u.
i m currently still in PG and may stay until this wednesday (due to a lot of order here have to supply/install) and then will go to handle my KL customers. I can install for u here at no extra charge. My showroom is in Midlands 1-Stop shopping complex 3rd floor number 22, Penang. u can call me b4 u come.
