Coil Upgrade? FBO N54 335xi

HKD126 · 08-30-2019, 02:17 PM

Just purchased an N54 335i. The car has already been nicely modded with:

BMS DCI
CPE chargepipe with HKS BOV
AA Race intercooler
CPE c@tlesspipes
Eisenmann race exhaust
BMS methanol kit with CM10 nozzle
RB PCV
BMS OCC
Etc.

I’m now just doing some maintenance work on the car and replacing plugs and coils. I figure I may as well upgrade to either the BimmerLife or Precision Racewerks coils. I’m going to soon put a set of PS2 DD’s on with inlets, so I figure it may be a good idea. Do either one of these coils out perform the other? They are about the same price, but am leaning towards the BL coils as I’ve been reading more posts about people having issues with the Precision’s.

Thanks!

Are you going over day 525hp?

That is the plan.

No issues with my precision setup. I would say do the precision with the coils on the intake manifold side so it is easier to change out the plugs.

Plug and play Eldor coils. Cheap, lifetime warranty from FCP and most running them are problem free.

I bit the bullet and just ordered the BimmerLife coils. Why not.
