Car Forum / Nissan / Nissan Cars / September 2005'94 Sentra - 1.6L - replace park plugs
Last time I replaced plugs I used Bosch Platinum #4418 plugs in my '94 Nissan Sentra. That was 75,000 miles ago. Any reason to use a different set of plugs? If so then what, genuine Nissan only? Mark Can't go wrong with Nissan replacements - they are most likely NGKs and can be bought from your local parts store. Your manual will probably have the correct part number. Cheers, Nirav 96 Max GLE, 120k bosch are the very worst choice you could have made, go with ngk and your problems will be solved > Last time I replaced plugs I used Bosch Platinum #4418 plugs in my '94 > Nissan Sentra.

Sounds to me like he got 75,000 miles out of these inferior brand of spark plugs. I didn't think they ("we", I work at Nissan) were making Sentra's that go 100,000 miles between tune ups back in '94? Maybe I missed that meeting. Anyway, I think Bosch's work quite well, especially in a car that's probably pushing or has passed 200,000 miles. I've always used them, and I haven't had any problems with Bosch... sounds like you do. I use Bosch Platinum +4's in my 1998 Frontier with 150,000 miles and get 24-27 MPG. I also use them in my 1990 Mazda MX-6 with 239,000 miles and get 26-32 MPG. I'd say those are pretty good numbers out of these inferior spark plugs. Note: sarcastic demeanor was meant. Al >>bosch are the very worst choice you could have made, go with ngk and your >>problems will be solved [quoted text clipped - 18 lines] > Note: sarcastic demeanor was meant. > Al I've also heard alot of bad raps for those BOSCH plugs. I always try to look at the flip side, though. As you've pointed out, the OP got 75K miles out of 'em, so he must be satisfied with that. I certainly would be. Perhaps the thing with the BOSCH plugs is that they are very critical of torqueing down, you TQ too much and one of its 4 tips will be way too close to the flying piston, wreaking havoc to your engine. Hell, I have BOSCH +2s in my wife's altima right now. I was getting the NGK, and while sitting at the counter at the auto store, the BOSCH plugs were in my face, and cheap to boot. So I tried them, and so far so good. In terms of feel, I get the very slight impression that the BOSCH plugs change the TQ curve, tilting it higher, in other words there's a bit more power up top and a little less in the middle. Just a gut feeling from being used to the car. With that kind of TQ change feul economy will go down because to get more oomfh out of the car you have to push it higher into the rpms. Feeling that, I may as well switch back to the NGKs next time. Did you notice a change in the TQ on your cars? CD The Bosch's have worked well, and may not even need replacement. I will replace the wires because a hole arc'ed through #3 and I had to fix it with electrical tape. I figured since they had 75K on them it might be a good time to replace them. What's so great about the NGK's that would make me want to use them?

In other words, genuine Nissan, so to speak. The engine was designed with the characteristics of those spark plugs in mind. I'll admitt I've substituted bosch in my cars as well. Never the +4s, though, just the +2s. Haven't had any bad experiences. I wonder if anyone notices a slight shift in the torque curve? With the OEM NGK, I tend to notice a stronger bottom end. With the Bosch, I noticed a slightly weaker bottom, but stronger top end. This has been my casual observation on the GA16DE and KA24DE motors. CD |
