The circles on the right are the injectors and the pipe at the back circled actually rises up to meet the hood so there is a lot of room under it. I already have the coils on hand, tried them a while ago and they fit fine.

Hi....the existence of the stock loops is a bit restricted at higher than stock strength and your situation will be unique. most say that they will wear out in some measure of miles. That may be 20k, 40k, 60k relying upon various elements. Assuming you run a blend of E85, more flash is most likely required, and so forth

In that sense my thinking is that I was because of redesign and getting a curl that has been tried to convey more flash when I intend to run e55 is a smart thought. My work was to make a moderate transformation choice for myself (and presently others).

It is already late here but no comprende either.

I think flash is spark and curl is something on the spring. But thats about it.

did some runs with the b58 coils and my setup (resistor in boots) with the SPP223E boots.
with my old bimmerlife kit i had a liiiiittle bit more corrections.
log shows a 850WHP Run

next step is to test them over more gears wot and higher boost level.

Awesome to see this working out well. I still need to trim up my resistors and put them in my boots.

Would there be any recommendations for Europeans on what ignition coil boots could be fitted? For example, a CPBK206 set from Ebay would cost about $ 75 when shipped and including taxes.
