Hi there - just wondering if someone could let me know what the suggested interval or expected lifespan would be to replace standard spark plugs (ie not long or extended life ones)?

My car has been into an AA Auto Centre for its regular service and it was raised the spark plugs need replacing at the next service. The spark plugs were replaced with standard ones approx 3000km ago (not by AA).

The car is a 2009 Hyundai i30 petrol variant. I am a little surprised this has been raised as an issue already - do I need to have any concern in getting them replaced ASAP or is this expected?

Thanks and look forward to hearing from you

Hi there,
Standard sparkplugs generally have an expected life of 30,000km and shouldn't really show signs of wear after just 3,000km unless they had been dropped, oil contaminated, or otherwise damaged. You are right to query why they need replacement, as I would not expect this as yet.

Hi Cade - thanks for the reply. Yes I'm a little surprised that it came up, I suspect I would have been told if the spark plugs had oil on them so don't think it's that. My spark plugs were last replaced due to a dead coil that stopped working, I'm guessing they could have inserted poor quality plugs as replacements? Is it worth getting a second opinion from another mechanic - or even replacing the plugs with long life ones for peace of mind? Thanks again

I recommend a second opinion, I think that standard plugs in some engines can show wear which can be classed as normal and without knowing that they were replaced recently might offer a suggestion of a check and assessment at next service if they have deteriorated further. the long-life plugs cost around 3-times as much but last around 90k.

Great thanks Cade - I think I'll take it back to the Auto Centre and ask them to put some long life ones in for peace of mind. It was also raised that the rear brakes were getting low and given we're doing a couple of road trips later this year - it's probably best I get everything running sound once and for all yeah? Appreciate your help so far
