Precision Raceworks Ignition kit install and custom intake

Pkeefe11 · 05-26-2022, 10:57 AM

Hi everyone,
I recently just picked up a precision raceworks ignition kit for my f25 and will be installing in the next few days. I'm taking some inspiration from another forum where someone created their own intake which mounts behind the grill in order the mount the coils. Not sure if people would be interested in following along but I'll be posting my process anyways!

I'd be interested in following if you're going to do before and after dyno charts to prove if all the money spent made a difference in performance

I got the kit to see if it would help combat the nasty warm start misfires I've got. Tried everything else, cleaning vanos solenoids, new spark plugs, nothing helped so hopefully these will. If not I'm running stage 2 on mhd so we'll see if there's any difference after reflashing.

Are certain cylinders showing misfire errors?

All of them upon warm starts, rpms fluctuate and the engines shudders. I know this is a common issue that other people have and bmw offers no solution. Tried to have it diagnosed at a dealer and they said there was nothing wrong.

Not sure why BMW says nothing is wrong even though you have misfire errors on all cylinders. With all cylinders misfiring, I'd check fuel delivery issues before swapping in expensive performance coil packs, maybe you have your reasons

have you replaced the Map sensor(s), and intake manifold gaskets oh and MAF sensor? I've seen that happen with bad intake manifold gaskets.

Cleaned the MAP and MAF sensor, honestly it only happens on warm starts, no misfires while driving, but I wanted to upgrade to these coils anyways to see if there was a performance difference and if they'd potentially cure the misfires. If not then oh well, for a car that has 250k miles and has been meticulous maintained I'm not too concerned about those few misfires.

Finished my install of the ignition kit as well as the intake reroute. Install went somewhat smooth with the coils but rerouting the intake was a little harder than expected. The coils are much better than the oem ones, mainly because I was due for new ones but the images are attached. Some of the set up is temporary for now and will be solidified in the future. (Also ignore the dirty engine bay lol).

I'm extremely interested in this intake setup..

Is there a way I can get the same parts? Did you get it all online or local?

So I reused the oem intake piping that houses the map or maf sensor. Then I used a few silicone elbows I bought on Amazon to connect the pieces. Finally went to advance autozone and got a spectre intake pipe and a cone intake. Feel free to pm me and I'll send screenshots.
