The flush product arrived, in purpose i bought one that is mixed with water after the coolant drain, i don't want to add anything in the coolant again, enough trouble i had. I will make few kilometres with the heat on (that's for the heater core) and then to the repair shop while it's stii warm for the drain.

"The term, Restomod, is a portmanteau of “restoration” and “modification”. It refers to the process of restoring and upgrading classic vehicles with modern components and technology. In recent decades, restomods have gained immense popularity among automotive enthusiasts. This is because they’re perfect options for those who seek to preserve the timeless beauty of their vintage car while enhancing the performance,comfort and safety too. Typically, a restomod involves replacing or upgrading various components such as the engine, transmission, suspension, brakes and interior features." That's the spirit !

Tomorrow the results from the first rest, City traffic (usual not hard as was in the 2nd), no boulevard no Highway, just a home to work route for about 25 km. I wish i could do more but with such a high temperatures it's difficult and the a/c use will ruin my Fuel Consumption. It was a small but useful test.

That's why the other countries are centuries ahead of us in GR which the latest 20 years we have adopted the German way of thinking: "Buy a new car, don't touch anything, go only to the official repair-shops, pay whatever they charge you and after 5-6 years sell it and buy from us the new model and do the same with it". You have compromised with this i don't.

Felicia air filter box designed from Czechs 40 years ago, i didn't change the diameter or the length of the hose that brings air to the throttle, i didn't touched the throttle itself. I already had that cone removed for many years and now i just refined the air flow.

It worthed every euro, read my first sentence of my signature.

It's because you can keep it at least for 5 years or is superior to the G12 in a specific sector?

If i done something and works i will mention it in public, i don't i will also mention it, there is no reason to hide anything. for example i had 48mm exhaust pipes and muffler, i had gain in high rpm but loses in low-middle, i admit it and when i found the chance i ask for 45mm installation, i lost something in high rpm and also mention it. I haven't see any Felicia driver to work inside his air filter box, i took a risk and i succeed, i admit that in 3rd gear and 2000 rpm in uphill the previous ''situation'' was one click better but i had to make a comprimise. I cut a part of that plastic cover, i always hate it, now i have better access to lubricate the throttle wire plus that cover and one plastic hook were pushing a bit that cable, not it's more ''free'' and i can also lubricate anytime i want the part of the cable that it's visible from the plastic hose till the bushing.

Only if are not made from quality steel. Are wrapped (till the lambda sensor) for about 20 years, checked 3 times till now for rust etc, no problems.

No, i have a custom one from A to Z. The @Thefeliciahacker said that i have lost performance but i proved to him that i haven't. The headers are wrapped with titanium tape for lower temperature inside the engine bay.

Help the mostly in high rpm by the way, already tested for a while in Highway. For sure in my summer trip but i will try for a test earlier.

The test was for 47.3 Km in hard City traffic conditions, in purpose quickly left the boulevard and engaged in traffic like a taxi driver, right lane, no overtakes, behind buses, waiting in bus stop etc. i wanted to see the car's behaviour now with the modified air filter box, now more air comes inside and has no restriction till the throttle. Last Sping when i had that damned-crappy 15W-50 the Fuel Consumption in such conditions was 12.9ltr/100Km (21.90 Uk MPG) and the worst was one night at 13.1ltr/100Km (21.56 Uk MPG). Now i have that tremendous Synthetic 10W-40, full repaired suspension, modified air filter box, 98 octane gasoline from different gas station than last year and the result in that ''torture" test was: This is the Average Fuel Consumption, 11.1ltr / 100Km or 25.45 Uk MPG This is the Total Fuel Consumption, the car burned 5.1 ltr gasoline for 47.3 Km distance or 10.78ltr / 100Km or 26.20 Uk MPG. I wish i could do more Km distance but it was noon, the sun was high, i was in sweat and i didn't want to open the a/c because i wanted to have similar situation with last year test. As for the difference between the 11,1 and the 10.78 i have to say that in Average function (with the ⌀ symbol) the TC-6 does not react so fast, takes time to make a change for more or less. In the Total with the Σ symbol (from the Greek word Συνολικη) is more accurate after a calibration and i have checked this 2 times in previous FC tests so i rely more in this function. Nevertheless the results are amazing (for my modified and heavy that stock car), keep in mind that some years back i had 14.7 ltr or 19.21 Uk MPg and take a look now, i have made a huge improvement and Yes, i don't regret even for a second that i have cut the engine cover and modified the air filter box, it worked !

Very interesting results for HEPU 12 (i already have G11 from that brand) in boiling time and the time that needs to get heated for 2 'C only. This G12 can be found in the local market, i wish the test had some other brands as Motul-SWAG-Febi-Valeo.

Who said the opposite? This would be my next project, i will try to locate that hole which @Papez mention long time ago 6U0129618 is the part code and i will make a modification. I can do anything working on the road side, i have to wait when the car is lifted for coolant flush to take photos and measure it.

I first installed that hose without having seen this video. Listen what he says at 4:19 ,so i did the right thin ! As we say here: ''Better late than never".

The reason that i reinstalled the hose from the grill to bring more air inside the air filter box is this: The photo is from a Julian Edgar's video. As for the results from the new test, well they were as the ones in the 1st test which means ''positive". In purpose i engaged in hard City traffic (behind buses or taxis, right lane mainly etc), i wanted to see the behaviour of the car (now were receives more air) when it's too hot and how the modified air filter box works in low rpm (low speed in traffic). I had to go in a boulevard for a while but i didn't wanted to stay long, i wanted to test the whole situation in hard City traffic with sun at noon in high temperatures. The car accelerates smoothly and the same happens when i release the gas pedal and the rpm drop, for example from 3rd gear i leave the gas pedal, little brake, put neutral and stop for a traffic light. No problem in City traffic, no hesitation, no abrupt behaviour and yes in 2000 rpm and 3rd gear in the same uphill things were not ideal but that is not a problem. The Fuel Consumption was lower that all the previous and i have photos to post as proof, i will make an Update soon.

The initial spot was there, before the factory one but there was an accident (Chinese metal...sigh) and i had to remove it from here. According to what @Papez wrote there https://www.briskoda.net/forums/topic/522126-three-g11-coolant-mixtures-boiling-cooling-time-comparison/?do=findComment&comment=5837357 the difference between the 3 solutions is very small, 30 seconds

Coolant comparison test | AUTODOC Interesting.

Can not translate them to Greek, no meaning. The factory takes indication from the coolant sensor and the after market from the lower hose, when the thermostat is closed of course shows much less, when the thermostat has opened and hot coolant returns to the expansion tank shows one click less because the lines on the factory are not so good in reading.

So no difference in performance? I mean in coolant, does get hot with more delay than G11?

@Thefeliciahacker what difference in performance you have seen now with G13 compared to the green G11 that you had?

OK, the "Official Skoda" repair shops here promote the G12 "because it's better for the sensors". They don't justify this but no one says in which sector is better compared to G11.

The left analogue gauge in the console reads the coolant temperature between the expansion tank and the radiator. Always is one click less than the one in the cluster.

G11, 80-85 'C thermoswich in radiator, 88 'C thermostat. I was in a fuel consumption test in City traffic, 1-2 o'clock at noon under sun.
