I have an early (1997) S1 Elise and somewhere along the years I've misplaced the original spark plug cover. It never really bothered me because it's lived in a garage (mostly) or at least under cover most of the time. I've read on here that the S2 cover fits (and does a better job of keeping rain out) - can anybody confirm this? Does it use longer bolts to fix? The S2 part number seems to be LDR000400 Apologies if there's a thread on this already, I did a search and found a mention of the S2 cover fitting but no details. TIA, Adam

I helped a friend install the engine in his S4 Esprit Turbo recently. It was an absolute pleasure, he was so well prepared. Here's a very short video: Paul

I have bought LED bulb kits to replace the existing poor halogen H1 and H7 bulbs. These are somewhat bigger beyond the lens due to inbuilt cooling fans. The H1’s dipped headlight have gone in nice and easy, but the main beam H7’s will not go in with the light fitting in situ. Has anyone had to remove the fitting and how easy is it to do? I think that the bulb kit will fit by removing the fitting, it just will not go in due to the angle needed to locate through back of the lens. Due to the bulkiness of the cooling fan and the angle of the inside of the clam it just will not pass. when refitting will I need a garage to realign the lights to make legal? Thanks …

Hi Everyone I am new to the forum and will be picking up an S3 Elise next weekend. Have previously had 5 Lotus cars M100 Elan SE M100 Elan S2 Elise 111R Elise R Exige S (Series 2) I am interested in fitting a navigation system to the car - something like this - Alpine - INE-F904D 1DIN Chassis – 9-inch Touch Screen, built-in Navigation, DAB+, HDMI and Apple CarPlay and Android Auto combatibility and would be interested to see if anyone else has gone down this route. I had them in one of the Elise's and the Exige previously but they were non airbag cars and I used a flip out screen which worked really well - just want to see people's …

Hi all. I've got an S1 with a K20 conversion that is currently sitting on ancient Yoko Advan Neova LTS (which aren't made anymore) that need to go in the bin. Sizes are 195/50R15 front and 225/45R16 rear. I'm finding that the 15 inch front wheels really limits the choice of tyres, especially combined with my desire for something road-biased. I understand later Elises had Yoko v105 as the OE spec but these aren't available for 15 inch rims. I contacted a Lotus dealership to see what they would normally recommend and they suggested Yoko AD08RS, but from what I can see this is a) more of a road-useable track-day tyre and b) really poorly reviewed following the change in comp…

Anyone know which TRD air filter is typically fitted to Elise S? Mines a 2013 if that's a factor. Edit: Toyota engine 1800 supercharged.

Hi everyone, Does anyone know how to remove an airbag steering wheel from a S3 Elise please? I've done a google search and it looks like they are attached with allen bolts rather than a nut so I assume this makes it easier to remove the wheel but I'm not sure on the process or how simple it is to do myself. I'm going to have my wheel recovered but would like to avoid leaving the car at the garage whilst this is completed. Thanks Simon

OK. I picked up my Lotus Elise S2 last Wednesday. By Friday afternoon, the front splitter had fallen off and IMHO is damaged beyond repair as I dragged it down the road under the car for 300 yards. Anyway............... This one was fitted by Paul Matty back in 2017 and is listed on the receipt as: Front Splitter in GRP (Elise S2). I liked it as it was quite subtle. Life is too short to mess around with this so I'm just going to get another and was wondering what people recommend.

Hi All, Having had my Elise for a whopping 25 years, it is currently producing about 160 bhp. I was hoping to get ITBs etc fitted, and as the car lives in North Wales DVA Power seemed to be a good choice, if not around the corner, but I am not sure if they are still taking work on? Are there many Midlands/NW choices for K Series tinkering? thanks in advance TH

Damsel in distress Hi Please can someone help as for months now I have had an engine warning light coming on intermittently on my Elise SC 2008. I have had new sensors and a new ECU but now the fault code has changed to P0172. It has passed the MOT, emissions are fine, it runs fine, tried putting in a new catalytic converter, but the warning light came on with that too. Fuel pressure checked and fine, temperature sensor reading fine, live data checked and fine. It is an intermittent fault, so appears after a few short drives and there is no pattern as to when the engine management warning light will come on. It is becoming a costly investigati…

Being an old fart, I'm not familiar with modern car technology. My Elise S3 ECU light is permanently lit. I know that this is a 'take to your friendly and expensive Lotus technician' scenario but I've heard that this is quite common. Oil level is fine, haven't changed fuel octane. Maybe air filter. Any feedback would be great. Also, advice on ECU reader suggestions would be appreciated. Thanks

Hi everyone, I know this has probably been done to death, but is there any update on whether anyone is putting together a list of people who need window seals, part numbers C117U0009F & C117U0010F, in case we can get a bulk buy discount? Many thanks.

I hope the MLOC Team can advise! The header tank cooling levels, on my 2002 S2 Elise, has started fluctuating 20mm below the min level, when cold, to just below the max level when warm. Images below (I hope) I’ve had the car from new and the coolant level has stayed consistent between the min and max levels until now!! There is no obvious coolant loss under the car and the oil dip stick and oil filler cap are just showing clean oil. I have changed the pressure cap but this has not changed the situation. Im not sure what my options are and PJS/Unit 4 are over an hours drive away and I’m reluctant to travel that distance!! Any help and or advise is…

A few days ago the engine management light came on on my 2008 Elise. My OBD reader said fault P0638 which is to do with the throttle control I believe. Have sprayed the throttle position sensor contacts with contact cleaner and removed the air inlet pipe, the valve rotates by finger when I push it and then rotates back when I release. The light has gone of and engine idling ok, but i'm getting this buzzing sound when the ignition is on, which goes away when the engine is started. Maybe the buzzing sound has always been there and I've never noticed. Is it normal ? 20230806_170618.mp4
