BMW F30 320i B48 Spark Plug change.. quite a task!

- After a long break, sofaBae needed some attention. The OEM spark plugs have been on for about 32k kms and were acting up leading to intermittent misfires and bad mileage.
Fortunately thanks to Kashif Nazim (a fellow 330i and VRS owner), who was able to source OEM 330i High Performance spark plugs that would hold up to heat and abuse better than the ones for the 320i, I got to the task of changing them out. The 330i is a higher output version of the same B48-B20 engine with slightly lower compression and better ignition components, so we decided to go with those.
Now came the incredible task of actually pulling half the top of the car apart to reach the 4th spark plug. I understand BMW designed the car to be 50-50 weight distribution, as a result of which the engine is pushed into the firewall as much as possible, but I sincerely hoped their engineers would be able to do that while keeping serviceability in mind. Also the un-necessary E-torx bolts thrown into the mix just go to complicate things further.
Finally after a lot of elbow grease the plugs were changed, and I managed to remove some of the heat/sound insulation that are standard on CBU cars but have no reason to be on Indian cars due to our tropical climate conditions. With that removed the turbo sound is much more apparent and the car feels a lot nicer to drive, in spite of the horrible luxury line suspension.
If I do decide to keep this car beyond 2021 January, we may go about getting a cup kit for the car and maybe an Evolve Tuning remap which claims to pump up the output by 80hp to about 270hp... lets keep our fingers crossed. - Авто та транспорт
Please post more b48 content dude you're killing it, love from America
Honestly not much to put. The 20i guide has such high compression that tuning it is risky.
I just wanted to say thank you for uploading this video, I just followed everything step by step today and changed the plugs on my 330i. If it wasn't for people like you who take the time to make these videos a lot of people like us would be stuck paying a dealership or small shop to do easy things like this and get overcharged in the process. So again, man thank you so much, from Florida with much respect and appreciation! If you end up replacing your own pads and rotors make sure you record it haha, I think that is probably what's coming up next for my maintenance. I am at 40k miles now.
Thank you very much, it is really great that guys like you take their time and record such detailed videos
I can watch these videos all day, post more !!!
Hahaah.. thanks bud!
Thank you for this video, it assisted me allot, most videos on the F30’s is not of the B48 engine and is different positioned.
Thank you very much my friend
nice video, good job
Much appreciated video. It's not as bad as it seems...just annoying. Bolts are easy to take off and put back. You were able to do this video in under 30 mins with edits...so you probably were able to complete in total about an hour and half or less right? I find working on my car...while listening to good music...relaxing a bit. And YES..BMW engineering is ridiculous. Hello from California!
Yes give or take an hour and a half. It’s just a tedious task, not too complicated
Nice video bro. Isn't it longitudinal layout? You had mentioned transverse. Well i guess they had mounted the engine such a way for 50/50 weight distribution and better centre of gravity. Mine's a 320d so I've not got this issue.
Yea it’s longitudinal..
You still need to change your glow plugs eventually
How often the spark plugs must be changed for this specific model, mine is from 2016 and has 40,000 kilometers, and I have that doubt.
mine were replaced at 31,000 kms, and were in pretty bad shape.
Hey man!
I soon need to change the spark plugs and i want to know the part nr from your spark plugs you put on. I dont know what bmw is saying about putting a 330i spark plugs on a 320i? Do they recommend it or not.
I have a 320i 2018
Yes, 330i plugs are recommended on the 320i in hot tropical climates.
@@PrithwiRay what part nr you got for the spark plug?
How have the new spark plug held up? Did the fuel economy or performance/power delivery change?
Improvement in fuel economy for sure
Power delivery is smoother, but that happens with all new plugs
What is the right wrench for the torx bolts (No.?)?
did you figure this out? gearing up to change mine in the coming week need to know what this is
Did you have issues with the OEM plugs? I have roughly 50000 km on my car and mine seem like they're failing early even though the service manual suggests that this should only be half of their life. I notice you have more than 10000km less than I and you're replacing yours already.
Yes I was having fuel efficiency and misfire issues. Spark plugs in our climate and traffic conditions will not last you. More than 25-30k. And bad plugs will eventually compromise your coil packs and those are not cheap...
What brand are the original spark plugs for this model
original ones are OEM Champion plugs for the B48, I upgraded to the NGK plugs from the 330i B48 HO motor. Those are OEM NGK.
Brilliant video. Have you had any issues with the pcv on the b48 engine?
none so far. almost 35k kms.
when BMW changed engine ??? you got this one changed too ?
The original engine had issues so it was changed under warranty at 14k kms
So most importantly how was the performance after putting NGK plugs?
Marginally better fuel economy, a bit more responsive engine. But I’m guessing that was due to the age of the oem plugs, rather than because of the upgrade
@@PrithwiRay ok. So bottom line.. not worth of the effort?
@@amilaandarage9734 unless u need to replace your current plugs, don’t look at this as an upgrade, more of a maintenance item.
Hi there, I bought spark plugs from BMW and it is NGK plugs with a BMW emblem on. 🤣
If you have smaller tools you don’t have to take the brace off!
It just makes life a lot easier, more space to work with…
@@PrithwiRay true, but it’s extra work while you can get it out quite easily with the right tools actually.
@@TheKookiemonster007I was gonna say the same thing. Plugs & coils replacement in my F30 took maybe 20min total.
still waiting for tvs tcu tune... dada
working on the video bro.
The real question that everyone must ask is - can it wreack "Tabahi" on the streets of New Delhi?
hahhaha.. not a chance with this motor. The high compression engine limiting peak boost combined with the chassis weight is the killer.. even at stage 1 power levels it was barely keeping ahead of a stage 2 Laura 1.8TSI.
What do you do for a living bro?
work bro :-p
Never pull spark plugs on a hot engine. Free advice, boss
Hot and warm have some difference bro..
Ye sab toh thike hai, ye ghar kitne sq yard ka hai lekin?😂
Ahahhahaha.. 1.5 acre
Everyone loves bmws until its time to do bmw shit
