Hello...
How are you doing?
I'm looking to upgrade the ignition of my M42 ti. I'm going to install magnacor wires but I don't know wich spark plugs should I buy...
What is, in your opinion, the best ones?
Also, will these upgrades bring any performance boost? Even if a small one?
Thank you!
regards! __________________ Portuguese 318ti

This is my question too...I found out that there r Denso iridium spark plugs IK20 for our engine but i wouldn't want to be the first who gets them in a ti..
Also what spark plugs do u use guys? i used the NGK BKR6EK (BMW recommended type) and they r pretty good. __________________

You wont make power with plugs. You could regain power by replacing old plugs with new. I use Bosche +4 on mine. The stock plugs were also a +4 design. I found no difference between the stock BMW plugs and the Bosche.
I personnaly would stay away from the Iridium plugs as they have been known to break, which has actually wrecked a couple of members engines.
On my race cars we use good old fashioned Champion copper plugs. The engines actually tested with a few more hp on the engine dyno with them. And they are cheap. We just replace them after every track session. | | | | | 01-04-2006, 03:26 PM | #4 | | aka Stabby Join Date: Nov 2004 Location: Mead, CO Posts: 5,336 |
my philosophy is just one of replacing them fairly often (yearly) and not so much what "the best" plug is. i just got the standard bosch plugs recommended by bmw as one of the stock plugs (they have both a bosch and an NGK recommendation). at something like $3-4 a plug, who cares? __________________ 1996 318ti, California package, 267k miles

No problem with them yet. I have about 20,000 miles on this set at the moment.
One thing I do before purchasing spark plugs is to inspect them at the parts counter. Look for torn up or bent packaging. Bent or off-center electrodes. Even check the gap to make certain they are correct for the car. Sometimes I will go through 6 or 7 boxes before I get plugs that meet my QA inspection. When I am questioned I make up some story about race cars and 200 mph... then they either laugh or shut up. Most people around here know of my Northstar V8 powered 200mph 1987 MR2. | | | | | 01-06-2006, 05:41 AM | #7 | | Senior Member Join Date: Dec 2004 Location: Muncie, Indiana Posts: 1,551 |
I used a BMW performance NGK 4 prong plug I really like it. I forget the part number though. | | | | | 01-06-2006, 10:16 PM | #8 | | Senior Member Join Date: Jan 2006 Location: Greece Athens Posts: 302 |
BKR6EQUP is the part number u mention. This is the "high power and long life" spark plug recomended by BMW __________________
