fuel injectors

been thinking of replacing my fuel injectors after watching videos from Raby and LN. Bosch says to use 62006 injectors. prices are all over the place. Rock Auto has about the best price. has anyone used these and are they authentic Bosch parts? Thanks

Why do you feel the need to replace them? I've had a lot of older cars and I don't think I've ever replaced an injector. Running a good injector cleaner in the tank once and again should keep them clean. If you're having issues and you suspect the injectors you can pull them and have them professionally cleaned, or have someone do an inline cleaning (they hook a cleaner system up to the fuel rail and basically run the car off a concentrated cleaning solution, this solved some rough running problems for my father on a BMW once). But in the absence of any notable problems I'd probably suggest just throwing in a bottle of fuel system cleaner and calling them good. Techron works well. BG44K is probably a bit stronger and I've had very good results with that.

Gubi those were my thoughts exactly. not had one problem at all and i do run fuel cleaner thru once every 6 months or so. but i have been watching the videos on you tube by Jake Raby and L&N engineering. they both you suggest you change the injectors for our age vehicle (and engine model) even if it has low miles. And they specifically say to put in new ones as opposed to having the old ones cleaned. it has to do with trying to prevent bore scoring. My car only has 40k miles on it and it runs fine but i would like to keep up with it in the best way possible. I assume these guy know what they are talking about.

I wouldn’t replace them… when I was racing cars I used www.injectors.com aka Marren Motorsports…they know their chit

To answer your original question, I bought my injectors from Rock Auto . The best I can tell they are genuine Bosch parts. They have the hologram and pass the number check on the Bosch website. I ended up buying quite a bit of stuff from Rock Auto for my rebuild. Starter, brakes, injectors, clutch. They had significantly lower prices on a lot of stuff compared to the normal places. I don't know if it's worth replacing them simply as a precautionary method. I've read that leaky injectors can create conditions that can lead to bore scoring. Basically they leak into the cylinder while the engine is off and end up scrubbing oil off of the cylinder so it starts dry, but I don't know if that's hard fact or just a pet theory that is getting thrown around. I know that when I pulled my engine apart for bore scoring, the top and bottom of the cylinder were scored pretty equally. It seems unlikely that fuel would be puddling at the top of the cylinder. You know, gravity and stuff. But if you're doing a lot of work in the area anyway, then maybe it's worth it. I'm going to go against the grain though and say that I think cleaning your old injectors is pointless. Modern fuel is already full of detergents, and gasoline is already a very good solvent to begin with. Your injectors will almost certainly never sludge up or get any kind of build up. The only thing that's likely to cause problems is if you get trash in your fuel lines that's too big to pass through the injector nozzles. If that gets in there, no liquid cleaner can help anyway, and if you are taking them out to be mechanically cleaned, you may as well just replace them given that they are over a decade old.

I replaced my injectors on a Benz with super high mileage because I was replacing the intake manifold and the injectors were right there. Got Bosch injectors from Rockauto and have no reason to believe they weren’t genuine. However, I have since had a big problem with Rockauto getting an order wrong and it was a horrendous mess. They literally do NOT have any customer support. There is no way to speak to anyone or even do so via email or chat. They have an online automated system for returns but it doesn’t have a place for comments. I had bought parts from Rockauto for many years and will never use them again because if an order gets messed up, it becomes a nightmare.

Rockauto is the ultimate dice throw, the parts are cheap but their return policy is none, they say the return policy works, it does not. Thank God I only used them for Ford parts and the only thing I got stung on was the serpentine belt. So I lost about 15 bucks throwing out a perfect one. Like you there was NO working return mechanism. I did find some secretary phone and left a message that I was lucky all the expensive things were correct because otherwise you get a beautiful alternator paper weight. I'll never use them again, ever.

Oops… it’s www.injector.com I had it as a plural… they will actually flow test and clean what you have if you need it done…

Thanks for the info on Rock Auto . i have bought a few things from them, namely filters, for a couple of cars with no issues. may have just been lucky but also not much money. also appreciate the other suggestions and info. as i said before, i have no issues with the car and am not planning for any other work in the engine bay, except my annual cleanup / winter checkup. (unless i find something then) but i got to watching the Jake Raby videos on you tube and it got me to thinking. he was not only talking about leaking injectors but also ones with poor spray patterns where the fuel may not completely atomize. a lot of the issue is from ethanol and other additives being in the gas. So i figured i would look in to it. once we get our first snow scare and the roads get treated, i put the car up anyway until i know the roads have been cleaned by a few rains. that could be until spring.

I suspect (wild *** guess actually) that cars that are taken off the road for extended periods of time are more likely to have injector issues. At the least for these cars - add a full dose of Stabilt or other decent quality fuel stabilizer in the tank and RUN the engine long enough for it to get to the injectors before packing it in mothballs for the winter. I avoid this issue by just using my car year-round. I'm too old to worry about it losing value and I'm certainly not preserving it for the next owner.

You’re considering Bosch 62006 injectors. RockAuto is generally reputable, but there’s always a small risk with online pricing that the parts may not be fully authentic. Genuine Bosch injectors should have the correct part number, packaging, and sometimes a holographic authenticity mark. Many users have successfully used RockAuto injectors without issues, but going through an official dealer is the safest way to ensure authenticity.
