Is it worth it to get the new xenon bulbs? Do they make that much of a difference?

 

a little but not really, they are still filament bulbs.I might sound like a broken record when it comes to headlights but i would just invest in the DDM Tuning HID kit, just my opinion

 

where can these be purchased ?? and how is the install?

 

the kit you need for the F4i is the 35w, H7 bulbs, and you can choose the spectrum.

Most ppl get the 35w. The 55w apparently produce a good amount of heat.. Alot of ppl select the 6000k or 8000k.. 6000k is going to give you the most light output with the slightest hint of blue at some angles.. The 8000k (which are what i have) look very blue, looking at them and they provide alot of light, just a bluer tone.. I think they just look sick though.

If you order, i heard somewhere that they ship out expedite orders first, so u may want to pay the extra however much to have them shipped via FedEx.. When i ordered mine, they had said they were out of stock, however they shipped out the next day. Its definitely money well spent though. Its 1000 times better than the stock lighting and for under $60, you cant go wrong..

Sick97ss did an amazing write up of the install.. super easy..
