Seen a few sites advertising these ngk coils with spark plugs any good???? Or cheap for a reason as would have thought ngk was a decent brand for plugs so why not coils???

 

If they are cheap, you might be getting just that....cheap goods. As for the name, if Ford atarted producing bread, would you buy it on the strength of their name or stick with bread from a firm specializing in baked goods?

 

Ford bread hell yea give me a 5.0 hot dog to go on that mustang bun with some royal purple catchup. Lmao.

 

Can you define "cheap"?

OEM coils from autoparts stores are "cheap" compared to from a dealer. Ebay coils are even cheaper, but also fraudulent.

 

Actually, you pretty much hit what I was getting at, the varying degrees of cheapness with the cheaper the item, the more likely the chance of a problem. I also wanted to stress that a brand name doesn't always indicate a quality item. Far too many companies have tried branching out from their specialty to market 'related" items, about which, they have no experience and, as a result, often produce an inferior product through that inexperience. Often it is best to stick with the tried-and-true names when buying goods as these proven brand names usually have decades of experience at producing their line(s) of products. If one wants to look for a deal, look for a distributor of time-tested items from reputable makers who is big enough to buy in bulk. Therein lies the ideal way to get a cheaper price on the item(s) needed.

 

ordered the ones recommended by several forums with the leada

 

BHR? If so, good choice, particularly if you plan on putting a lot of miles on the car and/or running it on a track. BHR has a great reputation for turning out high-quality coils that tend to last pretty near as long as the car does meaning less maintenance over the long-term.

these ones been recommended highly don't know if I can post links so delete if needs be, with the leads to match.

where has the DIY guide gone for fitting coils and leads I thought I found it but didn't save it?

 

Sounds, from the price, as though they are buying coils from Mazda to resell as a kit. If that is the case, you should be able to get reasonable life out of them. As for a link, try this one:

So have I got to remove the spark plugs to be able to do this? Thought I would be easier than them unless I'm reading it all wrong?

 

You only have to remove the plugs to replace them (recommended). The coils and wires can be done without unscrewing the plugs. However, it would be infinitely easier for both jobs to pull the front left wheel and access the area of the plugs through the wheel arch.

 

I have just replaced the stock units with the BHR ignition system and couldn't be happier. Hard to drop $500, but you get what you pay for. Very quality unit and easy installation. Frankly, I just purchased piece-of-mind with some added performance as a bonus.

 

Perfect as guy I got it off just replaced plugs but I'm replacing coils and leads as peace of mind and as per threads so I'll be cracking on with that
